Discrimination of dark matter models in future experiments

TL;DR

This paper explores methods to distinguish between different dark matter models using future experimental data, focusing on Higgs decay, electron electric dipole moments, direct detection, and collider searches.

Contribution

It identifies key experimental observables that can effectively discriminate among simple dark matter models in future experiments.

Findings

Higgs to two photons decay measurements are useful for model discrimination.

Electron electric dipole moment measurements help differentiate dark matter scenarios.

Direct detection experiments provide crucial information for identifying dark matter models.

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 and the electric dipole moment of the electron as well as the direct detection experiments are quite useful in discriminating particle models of dark matter. We also discuss the prospects of finding new particles in dark sector at the LHC/ILC.
