Impact of unitarity violation on sensitivity of the leptonic CP phase at Hyper-Kamiokande and DUNE
Journal of High Energy PhysicsWe study the impact of unitarity violation on the sensitivity of the leptonic CP phase, δ CP, considering the next generation of long-baseline neutrino experiments, Hyper-Kamiokande and DUNE.

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 ...

Searches for a Heavy Sterile Neutrino $N$ profit from precise predictions of inclusive decay rates, entering predictions for branching fractions and lifetime. Once decay channels into semi-hadronic final states are open, a reliable calculation of inclusive decay rates is only possible if $N$ is heavy enough to permit a perturbative calculation.

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-

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 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.

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,

Testing Heavy Neutral Leptons in Cosmic Ray Beam Dump experiments
Journal of High Energy Physics, 2023 In this work, we discuss the possibility to test Heavy Neutral Leptons (HNLs) using “Cosmic Ray Beam Dump” experiments. In analogy with terrestrial beam dump experiments, where a beam first hits a target and is then absorbed by a shield, we consider high-
