Low-Energy Supernovae Bounds on Sterile Neutrinos

open access: yes, 2023
Sterile neutrinos can be produced through mixing with active neutrinos in the hot and dense core of a core-collapse supernova (SN). The standard bounds on the active-sterile mixing ($\sin^2 \theta$) from SN arise from SN1987A energy-loss, requiring $E_ ...

Sterile neutrinos in string derived models [PDF]

open access: yes, 2018
The MiniBooNE collaboration recently reported further evidence for the existence of sterile neutrinos, implying substantial mixing with the left-handed active neutrinos and at a comparable mass scale.

Phenomenology of light sterile neutrinos [PDF]

open access: yes, 2017
Several anomalies recorded in short-baseline neutrino experiments suggest the possibility that the standard 3-flavor framework may be incomplete and point towards a manifestation of new physics.

Supernova gamma-ray constraints from heavy sterile neutrino decays

open access: yesJournal 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 ...

Second leptogenesis: Unraveling the baryon-lepton asymmetry discrepancy

open access: yesJournal of High Energy Physics
We propose a novel scenario to explain the matter-antimatter asymmetry by twofold leptogenesis, wherein heavy Majorana neutrinos exhibit temperature-dependent masses and engage in CP-violating decays.
