Abstract

The international accelerator neutrino experiment T2K (Tokai-to-Kamioka) began accumulating data in 2010 and has since then accomplished 10 runs in the neutrino and antineutrino modes. The present article reports on the latest results following from the analysis of these data and including the first ever 3\(\sigma\) constraints on the CP-violating phase \(\delta_{CP}\). Also, the plans for an upgrade of the near detector ND280 are surveyed.

Notes

  1. \(l\)-CCQE (Charged-Current Quasi Elastic) stands for the charged-current quasielastic neutrino scattering process \(\nu_{l}N\to lN^{\prime}\), where \(N\) and \(N^{\prime}\) are nucleons and \(l\) is a lepton—for example, \(\nu_{\mu}n\to\mu^{-}p\)—while \(e\)-CC\(1\pi^{+}\) stands for processes involving the production of at least one positively charged pion—for example, \(\nu_{e}N\to e^{-}N^{\prime}\pi^{+}\).
