Abstract:
As measurements of the neutrino oscillation parameters improve it is becoming more interesting to study antineutrino oscillations, to investigate CP and CPT violation in the lepton sector and nonstandard matter effects. We present the most recent T2K antineutrino oscillation results, from data collected using a νµ-enhanced neutrino beam corresponding to 4.01 × 1020 protons on target. The first analysis of νe appearance on T2K is presented, as well as world-leading measurements of the dominant oscillation parameters for νµ disappearance. T2K measures sin2 2θ23 = 0.46+0−01406 and ∆m232 = 2.50+0−032 × 10−3 eV2, which is consistent with previous T2K measurements of the neutrino oscillation parameters and existing antineutrino measurements.Measurement of the inclusive electron neutrino charged current cross section on carbon with the T2K near detector.

Abstract:
The T2K off-axis near detector ND280 is used to make the first differential cross-section measurements of electron neutrino charged current interactions at energies ∼1 GeV as a function of electron momentum, electron scattering angle, and four-momentum transfer of the interaction. The total flux-averaged ν(e) charged current cross section on carbon is measured to be ⟨σ⟩(ϕ)=1.11±0.10(stat)±0.18(syst)×10⁻³⁸ cm²/nucleon. The differential and total cross-section measurements agree with the predictions of two leading neutrino interaction generators, NEUT and GENIE. The NEUT prediction is 1.23×10⁻³⁸ cm²/nucleon and the GENIE prediction is 1.08×10⁻³⁸ cm²/nucleon. The total ν(e) charged current cross-section result is also in agreement with data from the Gargamelle experiment.Measurement of the neutrino-oxygen neutral-current interaction cross section by observing nuclear deexcitation γ rays
