متن کاملSZ effect from Dark Matter annihilation
We derive in this Letter the SZ effect induced by the secondary electrons produced in the annihilation of Weakly Interacting Massive Particles (assumed here to be neutralinos) in gravitationally bound structures dominated by Cold Dark Matter (CDM). We show that the DM induced SZ effect has a specific spectral shape and an amplitude which increases for decreasing neutralino mass Mχ. The availabl...
متن کاملSUSY spectrum constraints on direct dark matter detection
We perform an investigation of the MSSM parameter space at the Fermi scale taking into account available accelerator, non-accelerator and cosmological constraints. Extra assumptions about upper bounds for some of the SUSY particles are also imposed. We show that a non-observation of the SUSY dark matter candidates with a high-accuracy dark matter detector, such as Ge, under above-mentioned assu...
متن کاملNonabelian dark matter with resonant annihilation
We construct a model based on an extra gauge symmetry, SU(2)X×U(1)B−L, which can provide gauge bosons to serve as weakly-interacting massive particle dark matter. The stability of the dark matter is naturally guaranteed by a discrete Z2 symmetry that is a subgroup of SU(2)X . The dark matter interacts with standard model fermions by exchanging gauge bosons which are linear combinations of SU(2)...
