Abstract
We present a comprehensive study of Majorana dark matter in a \(U(1)_{B-L}\) gauge extension of the standard model, where three exotic fermions with \(B-L\) charges as \(-4, -4, +5\) are added to make the model free from the triangle gauge anomalies. We compute the dark matter observables in scalar and gauge portal context and make a parameter scan consistent with the current experimental limits. A massless physical Goldstone boson plays a key role in the scalar portal relic density. Finally, we briefly discuss the neutrino mass generation at one-loop level.
