Bounds on heavy sterile neutrinos revisited [PDF]

open access: yesJournal of High Energy Physics, 2005
We revise the bounds on heavy sterile neutrinos, especially in the case of their mixing with muon neutrinos in the charged current. We summarize the present experimental limits, and we reanalyze the existing data from the accelerator neutrino experiments and from Super-Kamiokande to set new bounds on a heavy sterile neutrino in the range of masses from

Heavy sterile neutrinos and supernova explosions [PDF]

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2009
We consider sterile neutrinos with rest masses ~0.2 GeV. Such sterile neutrinos could augment core collapse supernova shock energies by enhancing energy transport from the core to the vicinity of the shock front. The decay of these neutrinos could produce a flux of very energetic active neutrinos, detectable by future neutrino observations from a ...

Comprehensive constraints on heavy sterile neutrinos from core-collapse supernovae [PDF]

open access: yesPhysical Review D
Sterile neutrinos with masses up to O(100)  MeV can be copiously produced in a supernova (SN) core through the mixing with active neutrinos. In this regard, the SN 1987A detection of neutrino events has been used to put constraints on active-sterile neutrino mixing, exploiting the well-known SN cooling argument.

Sterile neutrinos

open access: yesPhysics Reports, 2021
Neutrinos, being the only fermions in the Standard Model of Particle Physics that do not possess electromagnetic or color charges, have the unique opportunity to communicate with fermions outside the Standard Model through mass mixing.

U(1) ′ mediated decays of heavy sterile neutrinos in MiniBooNE [PDF]

open access: yesPhysical Review D, 2019
The MiniBooNE low-energy excess is a long-standing problem which has received further confirmation with a reanalysis using newly collected data, with the anomaly now at the 4.8σ level.
