Heavy neutral leptons and top quarks in effective field theory

Journal of High Energy Physics
We study the phenomenology of heavy neutral leptons (HNLs) at the LHC in effective field theory, concentrating on d = 6 operators with top quarks.

Decays in Flight of Heavy Sterile Neutrinos in the MiniBooNE Detector

Journal of Physics: Conference Series, 2015
Heavy sterile neutrinos in the O(10) MeV mass range would be produced in neutrino superbeams, from pion and kaon decays. In short-baseline experiments and for sufficiently long lifetimes, such steriles can propagate to the detector and decay to electrons or photons, leading to signatures which may be mis-identified for oscillation driven electron quasi-

Supernova bound on keV-mass sterile neutrinos

, 2011
In this talk, I first explain why the keV-mass sterile neutrinos, slightly mixing with ordinary neutrinos, are interesting in particle astrophysics.

Sterile neutrinos as dark matter [PDF]

, 1993
The simplest model that can accommodate a viable nonbaryonic dark matter candidate is the standard electroweak theory with the addition of right-handed or sterile neutrinos.

Supernova gamma-ray constraints from heavy sterile neutrino decays

Journal of Cosmology and Astroparticle Physics
Abstract Heavy sterile neutrinos can be produced in core-collapse supernovae (CCSNe), which are superb particle generators because of their high densities and temperatures. If the sterile neutrinos are long-lived, these may be produced inside the supernova core and escape the stellar envelope, later decaying into SM particles like ...

Phenomenology of Sterile Neutrinos at different Scales

, 2012
Phenomenology of sterile Neutrinos at different Scales Sterile neutrinos are one of the most simple extensions of the Standard Model (SM), but they can still have a rich variety of phenomenological implications on physical observables.
