Vector SIMP dark matter with approximate custodial symmetry

Abstract We consider a novel scenario for Vector Strongly Interacting Massive Particle (VSIMP) dark matter with local SU(2) X × U(1) Z ′ symmetry in the dark sector. Similarly to the Standard Model (SM), after the dark symmetry is broken spontaneously by the VEVs of dark Higgs fields, the approximat...
