Heavy sterile neutrinos and supernova explosions [PDF]
Physics 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 ...

Probing heavy sterile neutrinos at neutrino telescopes via the dipole portal
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2023 The question of how heavy a sterile neutrino can be probed in experiments leads us to investigate the Primakoff production of heavy sterile neutrinos from ultrahigh-energy neutrinos via the magnetic dipole portal. Despite the suppression from the small magnetic moment, the transition is significantly enhanced by tiny t-channel momentum transfers ...

Comprehensive constraints on heavy sterile neutrinos from core-collapse supernovae
Physical Review DSterile 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.

Physics 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
Physical 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.

Signature of heavy sterile neutrinos at CEPC [PDF]
Physical Review D, 2018 We study the production of heavy sterile neutrino $N$, $e^+ e^- \to N ν({\bar ν})$, at the Circular Electron Positron Collider(CEPC) and its $ljj$ signal in its decay to three charged fermions. We study background events for this process which are mainly events coming from W pair production.

Study of two quasidegenerate heavy sterile neutrinos in rare meson decays [PDF]
Physical Review D, 2021 In this work, we study the lepton-number-violating processes of $K^\pm$ and $D^\pm$ mesons. Two quasi-degenerate sterile neutrinos are assumed to induce such processes. Different with the case where only one sterile neutrino involves, here, the CP phases of the mixing parameters could give sizable contribution.

Two-dimensional models of core-collapse supernova explosions assisted by heavy sterile neutrinos
Physical Review DCore-collapse supernovae can be a copious source of sterile neutrinos, hypothetical particles that mix with active neutrinos. We develop two-dimensional stellar core-collapse models that incorporate the mixing between tau neutrinos and heavy sterile ...
