$Z'$ Portal Dark Matter in $B-L$ Scotogenic Dirac Model
Abstract
In this paper, we perform a detail analysis on the phenomenology of portal scalar and Dirac fermion dark matter in scotogenic Dirac model. Unconventional charge is assigned to the right-handed neutrino in order to realise scotogenic Dirac neutrino mass at one-loop level, where three typical value are chosen to illustrate. Observational properties involving dilepton signature at LHC, relativistic degrees of freedom , dark matter relic density, direct and indirect detections are comprehensively studied. Combined results of these observables for the benchmark scenarios imply that the resonance region is the viable parameter space. Focusing on the resonance region, a scanning for TeV-scale dark matter is also performed to obtain current allowed and future prospective parameter space.
