Description
The T2K long-baseline experiment is located in Japan and is designed to study oscillations of muon neutrinos. T2K receives a beam of muon neutrinos peaked at 0.6 GeV that are produced at J-PARC accelerator complex by converting a beam of 30-GeV protons hitting a graphite target. Upon travelling 295 km, neutrinos are detected by the Super-Kamiokande water Cherenkov detector. Located at 280 m from the target, the near detector complex (ND280) provides information about un-oscillated neutrino flux, direction and interaction cross-sections. The T2K experiment observed electron neutrino appearance at Super-K with the significance of 7.3σ and measured the associated oscillation parameter θ13 for both normal and inverted mass hierarchies. In addition, by looking at muon neutrino disappearance T2K provided improved measurements of the θ23 and Δm232 parameters. The results of these measurements are presented as well as a brief summary of the neutrino cross section measurements. Future prospects of the T2K experiment are discussed.
