Description
I show that the dark Higgs Boson, which is often ignored in DM phenomenology, can play a crucial and important role by restoring unitarity and opening new channels for DM pair annihilation. These are demonstrated in a number of different examples: (i) the invisible Higgs decay width in vector DM with Higgs portal,(ii) scalar or fermion inelastic DM and the exothermic DM scattering for the Xenon1T excess,(iii) collider searches for the s-channel scalar mediators, and (iv) Higgs-portal assisted Higgs inflation.
