We investigate features of the sterile neutrinos in the presence of a light gauge boson Xµ that couples to the neutrino sector. The novel bounds on the active-sterile neutrino mixings |U`4|2, especially for tau flavor (l = τ), 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 (ν4 → ν`e+e−), we explore and constrain a parameter space for low energy excess in neutrino oscillation experiments.
