DOI: 10.1007/jhep06(2020)094
Abstract: The neutrino oscillation probabilities in vacuum and matter are discussed, considering the framework of three active and one light sterile neutrinos. We study in detail the rephasing invariants and CP asymmetry observables, and investigate the… read more here.

DOI: 10.1007/jhep10(2018)021
Abstract: A bstractThe light sterile neutrino, if it exists, will give additional contribution to matter effect when active neutrinos propagate through terrestrial matter. In the simplest 3+1 scheme, three more rotation angles and two more CP-violating… 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: 10.1103/physrevd.100.023533
Abstract: For active-sterile mixing to be responsible for the full relic abundance of dark matter additional new physics is needed beyond the keV-scale sterile neutrino itself. The extra ingredient we consider here is the presence of… read more here.

DOI: 10.1103/physrevd.101.055020
Abstract: Recent global fits to short-baseline neutrino oscillation data have been performed finding preference for a sterile neutrino solution (3+1) over null. In the most recent iteration, it was pointed out that an unstable sterile neutrino… read more here.
