Unfolding the dynamics of dark matter through its production mechanism

by Prof. Hyun Min Lee (Chung-Ang University)

We report the recent status on self-interacting dark matter with an emphasis on thermal production mechanisms in models with hidden gauge theories. We propose solutions to resolve the potential problems of strong couplings for SIMP dark matter and explain the hierarchy between self-scattering and annihilation cross sections of dark matter.
