Inelastic scattering of BDM as investigated by COSINE-100 | See below papers. | High energy interactions in both LS and NaI | Energy of the LS > 4 MeV No tagged muons Total energy of the NaI > 4 MeV No alpha events in the NaI | The background muon flux can mimic the BDM signal. Total expected muon flux Approximate area of the experiment is Giving a total muon flux of or 336034 counts over 3 years. | limit = 1.645 * sqrt(2*bg) = 1348 counts over 3 years = 1.23 counts/day Note: This is a very pessimistic estimate and the muon detectors should tag a significant number of these muons, reducing the background. Better estimates/simulations of the muon background and veto efficiency can further refine this limit. | Theo | Theo |
