Title:     Discovery of electron neutrino appearance in a muon neutrino beam by the T2K experiment

Abstract: Since its discovery, neutrino oscillation has been the subject of intense research mostly through the observation of neutrino disappearance. The Tokai-To-Kamioka (T2K) experiment, with its 295 km baseline in Japan between the J-PARC facility in Tokai and the Super-Kamiokande detector in the Kamioka observatory, was designed to measure precisely muon-neutrino disappearance but also observe for the first time electron-neutrino appearance in a muon-neutrino beam.  T2K is the first long-baseline experiment in which the far detector is not located on the neutrino beam axis. This "off-axis" configuration enhances the neutrino oscillation probability by narrowing the neutrino energy distribution. T2K also includes a near detector complex with an on-axis detector, INGRID, and an off-axis detector, ND280, in order to characterize the unoscillated neutrino beam. After three and a half year since its commissioning, T2K has accumulated enough data to confirm the first observation of a neutrino appearance channel.

Stimulants available 15 minutes before the talk.
