Abstract

A model containing an SU(2) single Dirac fermion DM alongside a singlet psuedoscalar mediator which forms portal to SM through Higgs. Both new particles are odd under Z_2. In this model, both fermion and psuedoscalar can be DM candidate simultaneously when psuedoscalar becomes accidentally scalar when its mass is less than twice the fermions mass.
