Recent results from the Tokai-to-Kamioka (T2K) experiment
Clarence Wret, University of Rochester,

The T2K experiment uses an intense (anti-)neutrino beam produced at J-PARC in Japan. The beam is sampled by a suite of near detectors close to production and a large 50kt far detector, with a baseline of 295km. T2K has made precision measurements of oscillation physics, contributed to better understanding of neutrino interactions, and searches for exotic phenomena—including the discovery of electron neutrino appearance, and producing world-leading constraints on neutrino oscillation parameters. Most recently, T2K has seen indications of CP violation in neutrinos in the PMNS description of neutrino oscillations, with approximately 1/3rd of its expected data. This talk will focus on recent neutrino oscillation results, and outline the next-generation upgrades to the experiment and its analyses.
