Abstract

We revisit the status of a Majorana fermion as a dark matter candidate when a
sequential Z' gauge boson dictates the dark matter phenomenology. Direct dark
matter detection signatures rise from dark matter-nucleus scatterings at bubble
chamber and liquid xenon detectors, and from the flux of neutrinos from the Sun
measured by the IceCube experiment, which is governed by the spin-dependent
dark matter-nucleus scattering. On the collider side, LHC searches for dilepton
and mono-jet + missing energy signals play an important role. The relic density
and perturbativity requirements are also addressed. By exploiting the dark
matter complementarity we outline the region of parameter space where one can
successfully have a Majorana dark matter particle in light of current and
planned experimental sensitivities.
