Status of 3+N Sterile Neutrino Fits

Tension among recent short baseline neutrino experiments has pointed toward the possible need for one or more additional mass splittings in the existing neutrino oscillation framework. This would require the addition of at least one sterile (non-interacting) neutrino to the current model. This work summarizes fits to world data of models which include one, two, and three sterile neutrinos in the ∼1eV2 range and provides motivation for future short baseline searches.
