Status of Sterile Neutrino Global Fits

A number of short-baseline neutrino oscillation experiments have observed anomalous results which are consistent with the existence of a high mass-squared splitting Δm² ≈ 1 eV² in the neutrino sector. This would require the existence of at least one additional, sterile, neutrino. At the same time, other experiments have seen null results that strongly constrain the parameters space for the simplest sterile neutrino model. This 3+1 ν model thus faces incompatibilities between these various experiments. We will discuss some recent results in the field of short-baseline oscillation experiments and how they fit into the overall global picture. We will then introduce other models into the global fits, and discuss how they affect the tensions seen.
