[Colloqium] Past present and future of neutrino oscillations in Japan - Claudio Giganti (LPNHE) TBC

Tuesday 21 Jun 2016, 11:00 → 12:00 Europe/Paris

In this seminar I will review the important discoveries done using Water Cherenkov detectors in Kamioka (Japan). The first of these detectors, KamiokaNDE, that took data in the eighties opened the way to the neutrino astronomy observing neutrinos produced in the core-collapse 1987a SuperNova. It also measured neutrinos produced in the atmosphere and in the Sun. The following detector, Super-Kamiokande, built in 1996, discovered in 1998 the phenomenon of neutrino oscillations by observing a deficit of muon neutrinos produced in the atmosphere. Super-Kamiokande is still taking data and it is used as the Far Detector of the T2K (Tokai-to-Kamioka) experiment, a long-baseline neutrino oscillations experiment in which muon neutrinos are produced by an accelerator. T2K observed for the first time the oscillations in appearance mode, by observing electron neutrino in the muon neutrino beam and is currently searching for CP violation in the leptonic sector. I will conclude the seminar describing the next steps of this program, that includes the full exploitation of T2K and the construction of a next generation water Cherenkov detector, Hyper-Kamiokande.
