2023 CDM Annual Workshop
Collaboratively striving for success
The third Centre Annual Workshop will be held on Wednesday 29th November - Friday 1st December 2023. The workshop will be held in person at the Stamford Grand Adelaide, in Glenelg, Adelaide, SA.
We are working on whether there will be a zoom option to view the presentations for people who cannot attend. Presentations will not be able to be given via zoom.

Session 1 |
| Session Chair - Tony Williams | Ballrooms 1 + 2 |
|
|
9:30-10:00 | 30 | 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. |
|
10:00-10:30 | 30 | 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. |

10:30-11:00 | 30 | Icebreaker activity | Anita Vecchies | 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. |

15:00-15:15 | 15 | 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. |

15:15-15:30 | 15 | 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. |

|
16:00-16:15 | 15 | Dark Galaxies in the WALLABY survey | Jeremy Mould | WALLABY is a survey of the southern hemisphere in neutral hydrogen with the Australian Square Kilometre Array Pathfinder. In the pilot survey we are finding that 1% of the detected galaxies have no optical counterpart. Dark matter inferred from the velocity field of the gas is the main component of these galaxies. |
|
16:15-16:30 | 15 | 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. |
