Description
The long-baseline world-leading experiment T2K (Tokai-to-Kamioka) studies neutrino oscillations and other neutrino properties. The experiment uses an intense beam of muon (anti)neutrinos produced at J-PARC in Japan and measured by the near (INGRID, ND280) and far (Super-Kamiokande) detectors. Currently the experiment has collected statistics corresponding to 14.93 $\times 10^{20}$ POT (protons on target) in neutrino-mode running and 7.62 $\times 10^{20}$ POT in antineutrino-mode. Simultaneous analysis of appearance and disappearance channels of (anti)neutrino oscillations allows one to measure the following parameters that govern the oscillations: $sin^2(\theta_{23})$,$\:$ $sin^2(\theta_{13})$,$\:$ $|\Delta m_{32}^2|$, $\:$$\delta_{CP}$$\:$ and the mass hierarchy. Combined with the measurements from reactor experiments the T2K data provide an exclusion of the CP conservation hypothesis at the 2$\sigma$ level. In this talk the recent status and results from the T2K experiment will be discussed as well as the future plans of the project.
