TL;DR
The T2K experiment has collected extensive neutrino data, reporting results on neutrino oscillations and potential hints on CP violation, with preliminary anti-neutrino findings contributing to understanding neutrino properties.
Contribution
This paper provides the latest results from T2K on neutrino oscillations, including electron neutrino appearance and muon neutrino disappearance, with comparisons to reactor experiments and preliminary anti-neutrino data.
Findings
Hints towards negative δ_CP phase with normal hierarchy
Consistent results with reactor ν_e disappearance experiments
Preliminary anti-neutrino oscillation results presented
Abstract
The T2K long-baseline neutrino-oscillation experiment accumulated approximately 11.0x10^20 POT (protons on target) data until June 2015. The results of \nu_e appearance as well as \nu_\mu disappearance for 6.57x10^20 POT neutrino beam data are reported. A comparison with the results of reactor \nu_e disappearance experiments provides possible hints toward negative \delta_CP phase with normal mass hierarchy. Preliminary results based on 4.04x10^20 POT anti-neutrino beam data are also presented.
