报告摘要：The Weakly Interacting Massive Particle (WIMP) paradigm provides an elegant explanation to dark matter (DM) via the freeze-out mechanism. It suggests that the DM particle has weak scale couplings to the Standard Model (SM) particles. This implies sizable scattering rates between local DM and nucleons, residual DM annihilation today in galaxies, and DM production at colliders. However, the null results from the above experiments cast doubt on the WIMP paradigm. We will first review the WIMP DM models, discuss how they can evade those constraints and the parameter space they are still allowed. Later, we will discuss the variant models which provides thermal DM candidates beyond the WIMP paradigm.
