Investigating DUNE oscillations sensitivity to sterile pseudo-Dirac neutrinos

Journal of High Energy Physics
We 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-

Phenomenology of Sterile Neutrinos at different Scales [PDF]

, 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.

Probing the mixing between sterile and tau neutrinos in the SHiP experiment

Journal of High Energy Physics
We 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.

Sterile Neutrinos as Dark Matter Candidates [PDF]

, 2021
In these brief lecture notes, we introduce sterile neutrinos as dark matter candidates. We discuss in particular their production via oscillations, their radiative decay, as well as possible observational signatures and constraints.In these brief lecture

eV-SCALE STERILE NEUTRINOS FROM 331-MODEL WITH FROGGATT-NIELSEN AND LINEAR SEESAW MECHANISMS [PDF]

, 2021
We consider the properties of sterile neutrino sector of an extension of the Standard Model, (SM) based on SU(3)C ? SU(3)L ? U(1)X gauge symmetry (331-model).

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 ...

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.

Exotic sterile neutrinos and pseudo-Goldstone phenomenology

, 2019
We study the phenomenology of a light (GeV scale) sterile neutrino sector and the pseudo-Goldstone boson (not the majoron) associated with a global symmetry in this sector that is broken at a high scale.

Sterile neutrinos in string derived models [PDF]

, 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.
