Keynote presentation - Status and prospects of underground Direct Detection experiments
...
Marc Schumann

The direct detection of dark matter particles scattering off a laboratory target is a way to probe the dark matter around us. I will briefly review the current status of the field and what is required to cover the entire accessible parameter space before irreducible neutrino backgrounds limit the detection sensitivity.

Keynote presentation - LHC summary talk
...
Paul Jackson
...
The ATLAS experiment at the Large Hadron Collider (LHC) is one of the most powerful tools in the search for dark matter. Dark matter is a mysterious substance that makes up about 85% of the matter in the universe, but it cannot be directly observed because it does not interact with light or other forms of electromagnetic radiation. However, dark matter does interact with ordinary matter through gravity, and this interaction can be indirectly detected by the ATLAS experiment.
One way that ATLAS searches for dark matter is by looking for events with large missing transverse momentum. Missing transverse momentum is a measure of the amount of momentum that is missing from an event. If dark matter particles are produced in a collision at the LHC, they will escape the detector without interacting with it, leaving behind a signature of missing transverse momentum. ATLAS has also conducted searches for dark matter by looking for decays of the Higgs boson into invisible particles and other invisible signatures. If the Higgs boson can decay into dark matter particles, it would provide a direct link between dark matter and the Standard Model of particle physics. To date, ATLAS has not found any definitive evidence for dark matter. However, the experiment has placed important constraints on the properties of dark matter particles. These constraints have helped to guide the development of new theories of dark matter, and they will continue to be important as the search for dark matter continues.
This talk will cover the contributions to searches being made by Centre researchers and discuss our efforts in work to upgrade the detector for future higher energy and intensity collisions at the LHC.

This will be a group activity on each table. We will ask the room a simple question and give each table a few minutes to discuss their answers. Then half the table (every second person) gets up and swaps to another table where you will answer the next question. And repeat until we have run out of time. The questions will be light (eg. What’s your favourite beverage?) and some with a bit of a physics focus (eg. what’s your favourite equation) it’s not mandatory for everyone on the table to answer every question.

Impact of nuclear structure on nuclear responses to WIMP elastic scattering
...
Raghda Abdel Khaleq
...
We build on previous work by investigating the sensitivity of nuclear response functions to nuclear structure for WIMP-nucleus elastic scattering, employing nuclear shell model interactions which differ from those used in previous literature to facilitate comparison between different nuclear structure results. This is performed for isotopes relevant to direct detection experiments:19F , 23Na, 28−30Si, 40Ar, 127I, 70,72−74,76Ge and 128−132,134,136Xe. Our integrated nuclear response values sometimes exhibit large (up to orders-of-magnitude) factor differences compared to those in previous works for certain WIMP-nucleus interaction channels and their associated isotopes. We highlight potential nuclear modelling uncertainties in WIMP-nucleus scattering amplitudes, and deduce the effect of these uncertainties on the scattering cross-sections associated with the XENON100 and LUX direct detection experiments for natXe isotopes.

Probing dark matter with gravitational waves
...
Giovanni Tomaselli
...
Future gravitational wave detectors will enable precision studies of black hole environments. Possible scenarios include: accretion disks, dark matter overdensities, or superradiant clouds of ultralight bosons. I will show how these environments alter the gravitational waveform, and how their characteristic imprint can allow us to identify them. I will then focus on the case of a cloud of ultralight bosons, discussing its properties, as well as its extremely peculiar gravitational wave signatures.

Improving ATLAS Hadronic Object Performance with ML/AI Algorithms
...
Albert Kong
...
Experimental uncertainties related to hadronic object reconstruction can limit the precision of physics analyses at the LHC, and so improvements in performance have the potential to broadly increase the impact of results. Hadronic object reconstruction is also one of the most promising settings for cutting-edge machine learning and artificial intelligence algorithms at the LHC. Recent refinements to reconstruction and calibration procedures for ATLAS jets and MET result in reduced uncertainties, improved pileup stability and other performance gains. In this contribution, selected highlights of these developments will be presented.

First science run results of XENONnT
...
Yajing Xing
...
The XENONnT experiment, situated at the Laboratori Nazionali del Gran Sasso in Italy, is a leading experiment in the search for Dark Matter (DM). With its 5.9-tonne liquid xenon time projection chamber, this experiment seeks to detect weakly-interacting massive particles (WIMPs) as the primary objective. Having achieved unprecedented purity and background level, it opens the door to exploring various other rare signals, such as solar axions, axion-like particles, bosonic dark matter, and even solar neutrinos. This talk will provide an overview of the XENONnT detector, its performance, and the key findings from its first science run.

Exploring light dark matter with the Migdal effect in hydrogen-doped liquid xenon
...
Alexander Ritter
...
An ongoing challenge in dark matter direct detection is to improve the sensitivity to light dark matter in the MeV-GeV mass range. One proposal is to dope a liquid noble-element direct detection experiment with a lighter element such as hydrogen, while another avenue is to exploit the Migdal effect, where a nuclear recoil leads to electronic ionisation or excitation. Combining these ideas we find that current and future liquid-xenon detectors doped with hydrogen could have sensitivity to dark matter masses as low as 5 MeV. Notably, this technique substantially enhances the sensitivity of direct detection to spin-dependent proton scattering, well beyond the reach of any current experiments.

Keynote presentation - Metrology summary talk
...
Michaela Froehlich
...
Nuclear recoils induced by dark matter interactions typically have energies in a region heavily affected by environmental radioactive and cosmic background. Thus, metrology activities are largely focused on how to measure radioactivity in detector materials and the associated laboratory environment. This talk will focus on the most important radioactive species likely to impact detector capability, namely K-40, I-129 and Pb-210.

Keynote presentation - WISP/Axion summary talk
...
Michael Tobar
...
The axion is a putative particle that should exist to solve the strong CP problem in QCD, and if it exists can be calculated to be created in the early Universe and can account for all the perceived dark matter. The axion is predicted to interact with standard model particles allowing various avenues for detection. If axions interact with photons, Maxwell’s equations of electrodynamics are modified through the chiral anomaly g_{aγγ}, and solving these equations in various situations has allowed the determination of a variety of experimental techniques to search for axion dark matter. We will review how electrodynamics is modified, and show how to calculate the sensitivity of a variety of experiments over a variety of mass ranges.
More recently interactions between putative axions and magnetic monopoles have been revisited, in this case the axion-photon coupling parameter space is expanded from one parameter to three (g_{aγγ}, g_{aEM}, g_{aMM}), allowing new ways to search for axions and a possible indirect way to determine if magnetically charged matter exists. We propose to undertake new experiments during the life time of this Centre, giving a new opportunity for significant alternative searches for dark matter.

SABRE South update
...
Phillip Urquijo
...
The SABRE (Sodium iodide with Active Background REjection) experiment aims to detect an annual rate modulation from dark matter interactions in ultra-high purity NaI(Tl) crystals in order to provide a model independent test of the signal observed by DAMA/LIBRA. It is made up of two separate detectors; SABRE South located at the Stawell Underground Physics Laboratory (SUPL), in regional Victoria, Australia, and SABRE North at the Laboratori Nazionali del Gran Sasso (LNGS).
SABRE South is designed to disentangle seasonal or site-related effects from the dark matter-like modulated signal by using an active veto and muon detection system. Ultra-high purity NaI(Tl) crystals are immersed in a linear alkyl benzene (LAB) based liquid scintillator veto, further surrounded by passive steel and polyethylene shielding and a plastic scintillator muon veto. Significant work has been undertaken to understand and mitigate the background processes, that take into account radiation from the detector materials, from both intrinsic and cosmogenic activated processes, and to understand the performance of both the crystal and veto systems. SABRE South will be assembled and commissioned in 2024/2025.
This talk will report the general status of SABRE South.

Cosmic dust as a dark matter discriminator
...
Adam Ussing
...
Cold dark matter models explain the large-scale universe to a high degree of accuracy, but tensions with observations persist. Warm dark matter has been proposed as an alternative to cold dark matter to solve tensions. To test this we used cold and warm dark matter simulations with different stellar physics prescriptions and used the dust as our metric to probe the underlying dark matter model from an observational standpoint.

We report the results of Phase 1b of The ORGAN Experiment, a microwave cavity haloscope searching for dark matter axions in the 107.42−111.93 µeV mass range. The search excludes axions with two-photon coupling gaγγ ≥ 4 × 10^−12 GeV^−1 with 95% confidence interval, setting the best upper bound to date. This result was achieved using a tunable rectangular cavity, and was the first axion search to be conducted with such a cavity.

Luminous Proton Loops Thermalise Light Dark Matter
...
Joshua Wood
...
The DM-proton elastic scattering cross-section is a benchmark search for many direct detection experiments. Given a non-zero cross-section with protons, dark matter would necessarily interact with photons at one-loop. These one-loop interactions can thermalise light dark matter during BBN, violating bounds on the effective number of relativistic species at this time. We calculate and present novel limits on the DM-proton elastic scattering cross-section due to this effect.

Hide and Super-Seek: Searching for Displaced Vertices with Missing Transverse Energy at the ATLAS Detector

Emily Filmer

Supersymmetry is one proposed extension to the Standard Model. It has been difficult to search for experimentally, given its low interaction with SM particles, however higher collider energies and increased data collection at the ATLAS Detector allow us to probe new and promising areas of phase space. This talk will outline the search for Displaced Vertices at the ATLAS Detector, using Missing Transverse Energy. Building on a previous analysis, we use new vertexing methods and better understanding of the detector backgrounds to enhance our sensitivity to long-lived gluinos.

FlameNEST: powerful statistical inference for the LZ and XLZD experiments
...
Robert James
...
FlameNEST is a novel approach to statistical inference for liquid xenon time projection chambers that enables the incorporation of higher-dimensional observable spaces and correlated shape-varying nuisance parameters in a computationally efficient manner. It is currently being for statistical inference and detector calibration fits enabling dark matter searches with the world-leading LUX-ZEPLIN (LZ) experiment, as well as for sensitivity studies towards a next-generation liquid xenon experiment within the XLZD consortium. In this talk, the principles behind the framework are presented, and examples of its use for both LZ and XLZD are given. We highlight future activities for both projects and the role that FlameNEST will play in each.

Global QCD analysis and dark photons
...
Nicholas Hunt-Smith
...
We performed a global QCD analysis of high energy scattering data within the JAM Monte Carlo framework, including a coupling to a dark photon that augments the Standard Model (SM) electroweak coupling via kinetic mixing with the hypercharge B boson. We first set limits on the dark photon mass and mixing parameter assuming that the SM is the true theory of Nature, taking into account also the effect on g – 2 of the muon. If instead we entertain the possibility that the dark photon may play a role in deep-inelastic scattering (DIS), we find that the best fit is preferred over the SM at 6.5σ, even after accounting for missing higher order uncertainties. The improvement in χ2 with the dark photon is stable against all the tests we have applied, with the improvements in the theoretical predictions spread across a wide range of x and Q2. The largest improvement corresponds to the fixed target and HERA DIS data, while the best fit yields a value of g – 2 which significantly reduces the disagreement with the latest experimental determination.

The Twisted Anyon Cavity Resonator as a Potential Dark Matter Detector and Sensing Device
...
Emma Paterson
...
The minimum axion mass detectable by existing photonic dark matter searches is set by the detector's frequency and hence size, which places the lower limit around 10^(−7) eV, leaving the ultra-light dark matter (ULDM) parameter space relatively unexplored. In this work, a new class of electromagnetic resonator is described; the Anyon Cavity Resonator, which has the potential to couple to ULDM
axions. This is possible due to the existence of a single electromagnetic mode with non-zero helicity, which is generated in vacuo through a pure photonic magneto-electric coupling of a transverse electric (TE) and transverse magnetic (TM) mode. The resonator is based on twisted hollow structures that possess mirror asymmetry. The origin of these high helicity modes is demonstrated using finite element simulation. It is predicted that these cavities will have the capability to search for dark matter down to 10^(−24) eV with a minimum coupling strength of 10^(−15.8) GeV^(−1); covering a completely unexplored region of parameter space.

Advancing stellar constraints on weakly interacting slim particles
...
Fred Hiskens
...
Stellar evolution has historically provided some of the strongest constraints on weakly interacting slim particles (WISPs), a collection of non-thermal dark matter candidates characterised by their light masses and feeble interactions with the Standard Model. Recent improvements in observational and theoretical astrophysics, combined with known limitations for several existing bounds, offer new opportunities for advancing these limits. This talk focuses on two examples of such advancements, namely our use of the $R_2$ parameter of globular clusters to provide the strongest constraint on the axion-photon coupling in a wide range of parameter space, and our improvements on existing static limits on dark photons using simulations of globular cluster stars.

Search for new physics in final states with objects originating from a top-quark, a charm-quark and large EmissT in pp collisions at √s=13TeV
...
Tristan Ruggeri
...
A search for the pair-production of stops decaying to c-quark, top-quark and neutralinos is reported using a pp dataset with an integrated luminosity of 139 fb−1 collected with the ATLAS detector at √s=13TeV. The signal is searched for in events containing several energetic jets, of which at least one is c-tagged, large missing transverse momentum and no charged leptons. This search is motivated by non-minimal flavour violation extensions of the minimal supersymmetric standard model.

In the context of the development of new technologies used for the Direct Search of Dark Matter with liquid xenon, my team at Subatech undertook the design of a Compton camera in order to initiate a potential widening of the impact of medical imaging. The project called XEMIS (XEnon Medical Imaging System) is based on an innovative instrument currently being installed at the Nantes University Hospital. During the workshop, I will present the motivations for this new technology, the targeted experimental results and also the main instrumental challenges. Scientific exploitation of the instrument and the first images are expected in 2024.

10:15-10:30 | 15 | A tale of two experiments and the not-so-straight journey of scientific endeavour | Laura Manenti | “It was the best of times, it was the worst of times…” Dickens’ words well describe the reality of experimental physics, where success and failure often go hand in hand. In this talk, I will take you through the development and characterisation of one of the world's quietest sensors: a superconducting transition-edge sensor designed for a future dark matter experiment searching for dark photons. I will tell you about the path that led to the final experiment and its outcome, sharing the challenges encountered along the way and the behind-the-scenes moments not shared in the final published paper. Through this tale, I will show that in experimental physics, the norm is that things do not unfold as planned. Yet, it is precisely this unpredictability that makes the journey so exciting. | |

11:30-11:45 | 15 | Dark Sector Searches at Belle/Belle II Experiment | Eiasha Waheed | The Belle and Belle II experiments are crucial for exploring the dark sector by searching for axion-like particles (ALPs) and heavy neutrinos, which may extend beyond the Standard Model. These searches focus on ALPs as potential dark matter candidates and study their decays, while also probing heavy neutrinos in B meson decays. With unprecedented sensitivity, Belle II pushes the boundaries on current dark matter and new physics searches, setting stringent limits on ALP couplings and neutrino properties. | |

15:30-15:45 | 15 | Galaxy clusters: giant dark matter particle colliders | Ellen Sirks | Galaxy clusters are the largest gravitationally bound structures in the Universe. Because of their high density and local velocity dispersion, they are ideal environments for probing the nature of dark matter. The specific properties of dark matter can have great effects on both clusters as a whole as well as on the galaxies residing in them. In this seminar I will present my work studying some of the effects of self-interacting dark matter on simulated galaxy clusters. In addition, I will discuss how I will be studying these effects observationally using the balloon-borne SuperBIT telescope. | |
15:45-16:00 | 15 | Development of Mass Spectrometry Techniques for Low Background Experiments | Dominik Koll | Mass spectrometry is the method of choice to determine radionuclide concentrations in detector materials for low background experiments if decay counting is not applicable. In this presentation, recent work to develop and optimise mass spectrometric techniques for the determination of radionuclides such as 40K, 129I, 210Pb or actindes will be discussed with focus on the future capabilities of the new Helmholtz Accelerator Mass Spectrometer Tracing Environmental Radionuclides (HAMSTER) facility. | |
16:00-16:15 | 15 | Mental well-being in gravitational wave and high energy physics | Kamiel Janssens | Many people in academia struggle with their mental well-being due to the unique environment and conditions. However, at the same time many researchers love their fulfilling job. In a recent set of survey(s) we probed the general mental well-being of researchers in the field of gravitational waves (2021) and the wider High Energy/Astrophysics community (2022). We start by highlighting some of the key conclusions of these surveys. Is there any difference between the subsequent years? How resilient is the mental well-being of our collaborators? Tune in to learn about these and many other related topics! | |
16:15-16:30 | 15 | Near-quantum limited axion dark matter search with the ORGAN experiment around 26 micro-eV | Graeme Flower | The latest iteration of the ORGAN experiment operated at millikelvin temperatures using a flux-driven Josephson parametric amplifier (JPA) for reduced noise, along with various other upgrades over previous iterations. Covering the 25.45−26.27 micro-eV mass range, this near-quantum limited phase of ORGAN employs a conducting rod resonator and a 7-T solenoidal magnet to place the most sensitive exclusion limits on axion-photon coupling in the range to date. | |

15:45-16:00 | 15 | Dark Matter Impacts, asteroids and primordial black holes | Jeremy Mould | Asteroid impacts have entered our consciousness as existential threats. What has been the impact of primordial black holes on the Galaxy's planets? Is there an anthropic constraint on PBH as dark matter? | |
16:00-16:15 | 15 | Status of the SABRE South Experiment | Lachlan Milligan | SABRE aims to provide a model independent test of the signal observed by DAMA/LIBRA through two separate detectors that rely on joint ultra-high NaI(Tl) purity crystal R&D activities: SABRE South at SUPL Australia and SABRE North at LNGS Italy. Ultra-high purity crystals are immersed in a liquid scintillator veto, further surrounded by passive shielding and a plastic scintillator muon veto. Significant work has been undertaken to assess and mitigate background from the detector materials, and to understand the performance of both the crystal and veto systems. The SABRE South muon detectors were commissioned in SUPL this year, with measurements of muon flux and angular distribution ongoing. These are the first detectors to be commissioned in SUPL. The physics program of SABRE South is also being developed, with basic sensitivity studies having been performed. Assembly of SABRE South is planned for the coming year. | |
16:15-16:30 | 15 | Asymmetric Dark Matter from semi-annihilation | Avirup Ghosh | Strong constraints from dark matter (DM) indirect detection observations have already shrunk the allowed parameter space for thermal WIMPs substantially. Asymmetric DM provides an alternative avenue to reconcile GeV-TeV scale DM with indirect detection observations. In this talk I shall show how a simple semi-annihilation like interaction can induce asymmetry in the DM which is further enhanced by the simple WIMP like pair-annihilation process. I shall also show how a concrete particle physics model allows such dynamics. | |
16:30-16:45 | 15 | Two-Higgs Models: a Possible Dark Matter Portal and 95 GeV Anomaly Candidate | Navneet Krishnan | Two-Higgs Doublet Models are a class of well-motivated Beyond Standard Model extensions, able to answer existing questions about the Strong CP Problem and Matter-Antimatter Asymmetry. I investigate the application of these models with an additional scalar singlet as a portal to WIMP dark matter, and to a series of anomalies at 95GeV at the LHC and LEP. | |
16:45-17:00 | 15 | An overview of CYGNUS' reach for dark matter and neutrino searches | Chiara Lisotti | As dark matter experiments grow in size and more of the available parameter space is investigated and excluded, it is necessary to plan ahead to circumvent the recently observed neutrino fog, which constitutes a near-irreducible background for an experiment sensitive to only recoil energy. The direction of the incoming flux of dark matter is unique, hence it provides a smoking-gun signal to unambiguously claim discovery; accessing this information would then make it possible to discern between dark matter and other sources. To accurately determine the origin of an incoming particle, a directional detector must be capable of resolving the spatial dimensions of the ionization tracks, for example micro-pattern gas detectors (MPGDs), which can be used as the readouts for gas time projection chamber (TPC)-based experiments; an example of such a set-up is CYGNUS. The CYGNUS consortium aims to build a global network of gas TPCs with both energy and directional sensitivity to reconstruct the signals event-by-event, to distinguish possible dark matter signals from the neutrino background from the Sun, as well as study the background itself and detect other feebly-interacting extraterrestrial particles. In this talk, I will give an overview of the physics potential of CYGNUS in terms of dark matter and neutrinos, and describe ongoing studies to derive the specifications needed to perform this search in future experiments. | |

11:15-11:30 | 15 | Collider Phenomenology of t-channel mediated Dark Matter Model | Aman Desai | We present the phenomenology at the Large Hadron Collider of a class of simplified t-channel Dark Matter models, in which coloured mediators from a new physics sector couple to Dark Matter candidates and Standard Model quarks of different flavours. We consider various realisations of such a class of models, characterised by different configurations of mediator and dark matter spins. We discuss the collider bounds on the masses of mediator and dark matter in such configurations by recasting experimental data from ATLAS and CMS searches through MadAnalysis 5. We also consider the impact of Next-to-Leading-Order corrections in the QCD sector on the determination of the bounds. This work is part of a joint effort between theorists and experimentalists to provide guidelines and benchmarks for new analyses during LHC Run 3. | |
11:30-11:45 | 15 | Using simulations of Milky Way analogues to test warm dark matter | Adam Ussing | Astrophysically, non-interacting dark matter is considered only by it's temperature, either cold or warm. Most models of galaxy formation work comfortably within a cold dark matter paradigm, but this isn't at the exclusion of all other models. We used tuned simulations of Milky Way type galaxies to produce similar observable satellite galaxy populations, and then search for differences in the dust. This has been shown to be possible for a single galaxy but we now test on a much larger sample. | |
