Search for light sterile neutrinos with the T2K far detector Super-Kamiokande at a baseline of 295 km

Abstract

Sterile neutrinos - neutrinos that do not directly participate in weak interactions - remain a vibrant possibility that could resolve a number of anomalies observed in neutrino experiments. The T2K Collaboration's latest analysis tests the hypothesis of a single light sterile neutrino. The negative results of their latest search set the strongest limits to date on the mass splitting and mixing angle probed by their long baseline experiment.
