Outline of Final Research Achievements

The dark matter may be unknown elementary particles, called as Weakly-intearcting massive particles (WIMPs), in physics beyond the standard model at TeV scale. We studied models beyond the standard model with the dark matter candidates, such as supersymmetric standard models and extended Higgs models, based on the LHC results. We also studied the nucleon-WIMP scattering cross section for the dark matter direct detection, the WIMP-pair annihilation cross section into gammas for the indirect detection, and also size of protohalos based on the WIMP hypothesis.
