Description
This talk presents results of fits of sterile neutrino models to short baseline oscillation data. This is motivated by a number of experiments that have observed anomalies. We report the latest 3+1 fit result, which is the model traditionally used for comparison. This model has a well-known “tension” between appearance and disappearance that we will discuss. We will then explore extensions to the 3+1 phenomenology, including introducing decay of the fourth mass state, that provide improved fits and reduced tension.
