Singlet fermion Dark Matter within Left-Right Model

Abstract

We discuss singlet fermion dark matter within a left-right symmetric model promoting baryon and lepton numbers as separate gauge symmetries. We add a simple Dirac fermionic dark matter singlet under SU(2)L,RSU(2)_{L,R} with nonzero and equal baryon and lepton number which ensures electric charge neutrality. Such a dark matter candidate interacts with SM particles through the extra ZB,Z_{B,\ell} gauge bosons. This can give rise to a dark matter particle of a few hundred GeV that couples to \sim TeV scale gauge bosons to give the correct relic density. This model thus accommodates TeV scale ZB,Z_{B,\ell} gauge bosons and other low scale BSM particles, which can be easily probed at LHC.
