We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting
views and insights from all disciplines involved—cosmology, astrophysics, nuclear, and …

In the classic type I seesaw mechanism with very heavy right-handed (RH) neutrinos, it is
possible to account for dark matter via RH neutrino portal couplings to a feebly interacting …

We propose a self-interacting inelastic dark matter (DM) scenario as a possible origin of the
recently reported excess of electron recoil events by the XENON1T experiment. Two …

We propose a minimal seesaw extension to simultaneously account for realistic neutrino
mass and mixing, the baryon asymmetry of the Universe via leptogenesis and a viable dark …

We propose a minimal model to simultaneously account for a realistic neutrino spectrum
through a type-I seesaw mechanism and a viable dark matter relic density. The model is an …

A bstract We study a generic leptophilic U (1) X extension of the standard model with a light
gauge boson. The U (1) X charge assignments for the leptons are guided by lepton …

Abstract An anomaly-free U (1) gauge extension of the standard model (SM) is presented.
Only one Higgs doublet with a nonzero vacuum expectation is required as in the SM. New …

A bstract We consider a minimal type Ib seesaw model where the effective neutrino mass
operator involves two different Higgs doublets, and the two right-handed neutrinos form a …

We propose the mass-varying dark matter (MVDM) model consisting of a scalar field and a
fermionic field interacting via a simple Yukawa coupling and containing an exponential self …

A bstract In an attempt to unfold (if any) a possible connection between two apparently
uncorrelated sectors, namely neutrino and dark matter, we consider the type-I seesaw and a …
