Description
The long-baseline neutrino experiment T2K uses one of the most intense and well understood GeV-scale neutrino sources in the world, combined with excellent detection capabilities using its near and far detectors. Beyond its primary goal of studying the standard 3-neutrino mixing model, it also provides an opportunity to search for exotic physics in the neutral lepton sector.
From both theoretical and experimental standpoints neutrinos are the least understood of the Standard Model Fermions, so they are a promising sector to look for new physics. A familiar but unresolved question is whether there exist light sterile neutrinos that would produce new oscillation signatures, but there is also the possibility of heavy neutral leptons that would be kinematically distinct. Other searches involving neutrinos that can be performed with T2K will also be covered, such as making use of the long baseline to look for violation of Lorentz invariance.
