T2K Experiment and latest results

A presentation on the T2K (Tokai-to-Kamiokande) experiment and the latest results is given. The T2K which started collecting data in 2010, is an accelerator-based long-baseline neutrino experiment placed in Japan. Its original goal is to discover the transition of muon neutrinos to electron neutrinos, which had been completed in 2013. Since then, T2K physic potential has been re-evaluated and searching for CP violation in the lepton sector is one of the central targets of the T2K. In summer 2017, with 2.25 x 10^21 POT, T2K firstly reported that CP-conserving values of parameter δCP in the PMNS mixing matrix lie outside 2σ region. During the last run period from Oct. 2017 to May 2018, thanks to a stable operation at 490 kW beam power, statistic data set in anti-neutrino mode is doubled and sensitivity to CP violation is thus increased to an unprecedented level.
