Description of the process and references to literature

Signature

Production of spontaneous radiation emission from charged particles

Differential rate dR/dLmddE= k * Lmd/E valid in range 10-1000 keV

Assumption: formula is valid down to 1 keV

Selection

1 crystal with energy [1,20] keV. Background rate above 20 keV too high to add anything significant

No energy in liquid scintillator

Background rate

0.4 cpd/keV/kg

-->

400000 counts in 3 yearsType of interaction

Differential rate as required (e.g. recoil energy, theory parameters, time)

Selection

Define requirements for each detector (energy range, multiplicity)

Background rate

Estimate background counts for 3 years of data taking and 50 kg of NaI crystal mass

Limit on signal rate

<1500 counts

-->

< 0.001 cpd/keV/kgDiscovery/exclusion limits based on background rate

Limit on model parameters

lambda< e-13s

Current limits

lambda< e-11s must add reference

Spontaneous radiation emission

dR/dLmddE= k * Lmd/E

in range 10-1000 keV

assume is valid form 1 keVFrom signal rate limits and differential rate formula

Current limits

Best limits from literature (overall and same type of detector) with references
