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

We investigate the early Universe production of sterile neutrino Dark Matter by the decays of
singlet scalars. All previous studies applied simplifying assumptions and/or studied the …

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 …

We construct a B− L model with A 4× Z 3× Z 4 flavor symmetry that accounts for the recent 3+
1 active-sterile neutrino data. The tiny neutrino mass and the mass hierarchy are obtained …

Motivated by the recent resurrection of the evidence for an eV scale sterile neutrino from the
MiniBooNE experiment, we revisit one of the most minimal seesaw model known as the …

We propose a non-renormalizable BL model with S 3× Z 4× Z 2 symmetry which successfully
accommodates the current active–sterile neutrino mixing in 3+ 1 scheme. The S 3 flavor …

A bstract We extend the Dirac Scotogenic model with the aim of realizing neutrino masses
together with the mass of a keV-scale dark matter (DM) candidate via the same one-loop …

The presence of a zero texture in the neutrino mass matrix can indicate the presence of an
underlying symmetry which can generate neutrino mass and mixing. In this paper, for the …

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is
the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter …

We attempt to simultaneously explain the recently observed 3.55 keV x-ray line in the
analysis of XMM-Newton telescope data and the Galactic Center gamma ray excess …
