We point out a novel role for the Standard Model neutrino in dark matter phenomenology where the exchange of neutrinos generates a long-range potential between dark matter particles. The resulting dark matter self interaction could be sufficiently strong to impact small-scale structure formation, without the need of any dark force carrier. This is a generic feature of theories where dark matter couples to the visible sector through the neutrino portal. It is highly testable with improved decay… Expand

Dark matter produced from neutrinos
In the presence of interactions between neutrinos and dark matter (DM), DM can potentially be produced via freeze-in from the neutrino sector. We investigate the implications of such a scenario forExpand
Speeding Up Dark Matter With Solar Neutrinos
We present a novel mechanism of using solar neutrinos to speed up dark matter, inspired by the fact that neutrinos are the most energetic particles from the Sun with a well-understood spectrum. In aExpand

We study the cutoff for the cosmic-ray neutrino, set by the scattering with cosmic background neutrinos into dark sector particles through a neutrino portal interaction. We find that a largeExpand
The Role of Sterile Neutrinos in Cosmology and Astrophysics

Naturally light sterile neutrinos in gauge mediated supersymmetry breaking
Moduli are generic in string (M) theory. In a large class of gauge-mediated Supersymmetry breaking models, the fermionic components of such fields have very light masses, around the eV scale, andExpand
Self-interacting Dark Matter Without Direct Detection Constraints
Abstract We explore the self-interacting dark matter scenario in a simple dark sector model where the dark matter interacts through a dark photon. Splitting a Dirac fermion dark matter into twoExpand

Probing the sterile neutrino portal to Dark Matter with γ rays
Sterile neutrinos could provide a link between the Standard Model particles and a dark sector, besides generating active neutrino masses via the seesaw mechanism type I. We show that, if dark matterExpand
Naturally light sterile neutrinos from theory of R-parity
Abstract The fate of R-parity is one of the central issues in the minimal supersymmetric standard model (MSSM). Gauged B − L symmetry provides a natural framework for addressing this question.Expand
