Connecting Dark Gauge Symmetry to the Standard Model

Abstract

Dark matter is postulated to be a neutral Dirac fermion, charged under a dark $U(1{)}_D$ gauge symmetry. Scalar partners of the quarks and leptons are also charged under $U(1{)}_D$. The dark gauge boson $Z_D$ and the dark Higgs boson $h_D$ enable either freeze-out or freeze-in mechanisms to account for the correct dark matter relic abundance. Dark number $D$ is connected to baryon number $B$ and lepton number $L$ through $D=3B+L-(2j{)}_{[mod2]}$ where $j$ is the intrinsic spin of the particle.
