Search for sterile neutrino with light gauge interactions: recasting collider, beam-dump, and neutrino telescope searches

Abstract

We investigate features of the sterile neutrinos in the presence of a light gauge boson $X^{\mu }$ that couples to the neutrino sector. The novel bounds on the active-sterile neutrino mixings $|U_{\ell 4}{|}^2$, especially for tau flavor ($l=\tau$), from various collider and fixed target experiments are explored. Also, taking into account the additional decay channel of the sterile neutrino into a light gauge boson (${\nu }_4\to {\nu }_{\ell }{e}^{+}{e}^{-}$), we explore and constrain a parameter space for low energy excess in neutrino oscillation experiments.
