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-

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 ...

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

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.

Light Sterile Neutrinos

, 2016
The theory and phenomenology of light sterile neutrinos at the eV mass scale is reviewed. The reactor, gallium and Liquid Scintillator Neutrino Detector anomalies are briefly described and interpreted as indications of the existence of short-baseline ...

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.

Heavy Sterile Neutrino Decay at Short-Baseline Experiments

, 2020
We studied a neutrino decay scenario as a potential solution to conciliate the tension between appearance and disappearance data at the short-baseline experiments. Particularly, we considered a heavy neutrino mass-eigenstate that decays into a usual light neutrino plus a massless scalar.

Tree-level UV completions for N R SMEFT d = 6 and d = 7 operators

Journal of High Energy Physics, 2023
We study ultra-violet completions for operators in standard model effective field theory extended with right-handed neutrinos (N R SMEFT). Using a diagrammatic method, we generate systematically lists of possible tree-level completions involving scalars,
