DOI: 10.1007/jhep04(2022)057
Abstract: Abstract Large numbers of τ leptons are produced at Belle II. These could potentially decay into sterile neutrinos that, for the mass range under consideration, are typically long-lived, leading to displaced-vertex signatures. Here, we study… read more here.

DOI: 10.1088/1475-7516/2018/10/055
Abstract: In this work we revisit the question of whether Cosmology can be made compatible with scenarios with light sterile neutrinos, as invoked to explain the SBL anomalies, in the presence of self-interaction among sterile neutrinos… read more here.

DOI: 10.1088/1475-7516/2019/12/047
Abstract: The detection of a sterile neutrino could constitute the first observation of a particle that could have been produced before Big-Bang Nucleosynthesis (BBN), and could provide information about the yet untested pre-BBN era. The cosmological… read more here.

DOI: 10.1103/physrevd.101.083521
Abstract: Short baseline neutrino experiments, like LSND and MiniBooNE experiments, pointed towards the existence of eV mass scale sterile neutrinos. To reconcile sterile neutrinos with cosmology self interaction between sterile neutrinos has been studied. We analysed… read more here.

DOI: 10.1103/physrevd.102.113014
Abstract: We determine the sensitivities of short-baseline coherent elastic neutrino-nucleus scattering (CE$\nu$NS) experiments using a pion decay at rest neutrino source as a probe for non-unitarity in the lepton sector, expected in low-scale type-I seesaw schemes.… read more here.

DOI: 10.1103/physrevd.105.035001
Abstract: The existence of light sterile neutrinos, as predicted in several models, can help to explain a number of observations starting from dark mater to recent anomalies in short baseline experiments. In this paper we consider… read more here.

DOI: 10.1103/physrevd.107.073005
Abstract: We scrutinize the hypothesis that gauge singlet fermions -- sterile neutrinos -- interact with Standard Model particles through the transition magnetic moment portal. These interactions lead to the production of sterile neutrinos in supernovae followed… read more here.
