A minimal dark matter interpretation for the CRESST-II signal
Abstract We report on the possible interpretation of the two proposed dark matter mass values m χ=11.6 GeV and m χ=25.3 GeV from CRESST-II within the framework of the Higgs portal minimal dark matter model. We find that the higher mass value yields a suitable fit with a dark matter-Higgs coupling η/...

| description | Abstract We report on the possible interpretation of the two proposed dark matter mass values m χ=11.6 GeV and m χ=25.3 GeV from CRESST-II within the framework of the Higgs portal minimal dark matter model. We find that the higher mass value yields a suitable fit with a dark matter-Higgs coupling η/2=0.157 and a recoil cross section which is compatible with contemporary estimates of the effective Higgs–nucleon coupling. On the other hand, the lower mass solution would require a large strangeness component in the nucleon to explain the corresponding nucleon recoil cross section reported by CRESST-II. |
