T2K Status, Results, and Plans

Wascko, Morgan

T2K is an accelerator-based long-baseline neutrino experiment in which a muon neutrino beam produced by JPARC in Tokai is sent 295 km across Japan to the Super-Kamiokande detector to study neutrino oscillations via the disappearance of muon neutrinos and the appearance of electron neutrinos. The T2K beam can be run in neutrino or antineutrino mode. Since the start of operations in 2010, T2K has conclusively observed muon neutrino to electron neutrino oscillations, and performed the most precise measurement of the muon neutrino and antineutrino disappearance parameters. These measurements are a new probe of unknown physics, including the possibility of observing CP violation in neutrino mixing. T2K has collected new neutrino and antineutrino data since the Neutrino 2016 conference. In this talk, we will present updated neutrino and antineutrino oscillation results with new data, and touch on other physics topics. Finally, the future prospects of the experiment, including the extension of the T2K program, T2K-II, will be presented.
