Descripción
We investigate the possibility that the dark matter is a chiral fermion charged under a global $U(1)_{B-L}$ symmetry spontaneously broken, which only interacts with sterile neutrinos via a scalar field mediator, singlet under the Standard Model gauge group.
We analyze in detail the phenomenological prospects for probing such scenario, namely
constraints from the observed dark matter relic density, direct and indirect dark matter searches and new Higgs decay channels.
We show that the dark matter annihilation cross section into sterile neutrinos can lead to the correct relic abundance by freeze out in a sizable range of the parameter space of the model, consistent with all current observations.
