Explaining LSND by a decaying sterile neutrino [PDF]
, 2005 We propose an explanation of the LSND evidence for electron antineutrino appearance based on neutrino decay. We introduce a heavy neutrino, which is produced in pion and muon decays because of a small mixing with muon neutrinos, and then decays into a ...

Investigating DUNE oscillations sensitivity to sterile pseudo-Dirac neutrinos
Journal of High Energy PhysicsWe explore the sensitivity of the Deep Underground Neutrino Experiment (DUNE) to sterile neutrino oscillations within a 3+(pseudo-Dirac pair) framework. We first consider a pair of two sterile neutrinos forming a pseudo-Dirac pair, then we consider a low-

New Clues about light sterile neutrinos: preference for models with damping effects in global fits
Journal of High Energy Physics, 2023 This article reports global fits of short-baseline neutrino data to oscillation models involving light sterile neutrinos. In the commonly-used 3+1 plane wave model, there is a well-known 4.9σ tension between data sets sensitive to appearance versus ...

Bounds on heavy sterile neutrinos revisited
, 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

Probing the mixing between sterile and tau neutrinos in the SHiP experiment
Journal of High Energy PhysicsWe study the expected sensitivity to the mixing between sterile and tau neutrinos directly from the tau neutrino disappearance in the high-energy fixed target experiment.

MeV sterile neutrinos in low reheating temperature cosmological scenarios
, 2008 It is commonly assumed that the cosmological and astrophysical bounds on the mixings of sterile with active neutrinos are much more stringent than those obtained from laboratory measurements.

Three Active and Two Sterile Neutrinos in an E_6 Model of Diquark Baryogenesis [PDF]
, 2000 In the U(1)_N extension of the supersymmetric standard model with E_6 particle content, the heavy singlet superfield N may decay into a quark and a diquark as well as an antiquark and an antidiquark, thus creating a baryon asymmetry of the Universe.

Long-lived heavy neutral leptons from mesons in effective field theory
Journal of High Energy Physics, 2023 In the framework of the low-energy effective field theory of the Standard Model extended with heavy neutral leptons (HNLs), we calculate the production rates of HNLs from meson decays triggered by dimension-six operators.

Probing leptogenesis with GeV-scale sterile neutrinos at LHCb and BELLE II
, 2014 We show that existing laboratory experiments have the potential to unveil the origin of matter by probing leptogenesis in the type-I seesaw model with three right-handed neutrinos and Majorana masses in the GeV range. The baryon asymmetry is generated by
