摘要: We propose a model where sterile Majorana fermion with mass in the range of 10 GeV-1 TeV can account for whole amount dark matter Universe. The involves right-handed singlet as weakly interacting massive particle, charged and neutral scalar, all singlets by standard symmetry makes use discrete order to guarantee stability. Also, motivated recent results reported CoGeNT CDMS-II experiments concerning excess events expected background, intriguing annual modulation observed DAMA, we look possible explanation some these experiments. Our show that there is lot room parameter space make this viable candidate, and, if it realized nature, also capable explaining DAMA signal and/or or event candidates. Besides, light Higgs boson preferred scenario.
