Discrimination of dark matter models in future experiments

Abstract

Phenomenological aspects of simple dark matter models are studied. We discuss ways to discriminate the dark matter models in future experiments. We find that the measurements of the branching fraction of the Higgs boson into two photons, the electric dipole moment of the electron, and the direct-detection experiments are quite useful in discriminating particle models of dark matter. We also discuss the prospects of finding new particles in the dark sector at the LHC/ILC.
