Self-interacting vectorial dark matter in a SM-like dark sector

Year: 2024

Type: article

Abstract: A dark SU(2) D × U(1) D gauge-Higgs sector, an exact copy of the Standard Model (SM) one, is proposed. It is demonstrated that the dark gauge bosons 𝒲(p,m), in analogous to the SM W ±, can fulfill the role as a self-interacting vector dark matter candidate, solving the core versus cusp and missing satellites problems faced by the conventional paradigm of collisionless weakly interacting massive particle. Constraints from collider, astroparticle and cosmology on such a self-interacting vector dark matter candidate are scrutinized. Implications for the future searches of 𝒲(p,m) in direct detection experiments are discussed.
