Measurements of the and -induced Coherent Charged Pion Production Cross Sections on by the T2K experiment
We report an updated measurement of the -induced, and the first measurement of the -induced coherent charged pion production cross section on nuclei in the T2K experiment. This is measured in a restricted region of the final-state phase space for which GeV, and , and at a mean (anti)neutrino energy of 0.85 GeV using the T2K near detector. The measured CC coherent pion production flux-averaged cross section on is . The new measurement of the -induced cross section on is . The results are compatible with both the NEUT 5.4.0 Berger-Sehgal (2009) and GENIE 2.8.0 Rein-Sehgal (2007) model predictions

Updated T2K measurements of muon neutrino and antineutrino disappearance using 3.6 10 protons on target
International audienceMuon neutrino and antineutrino disappearance probabilities are identical in the standard three-flavor neutrino oscillation framework, but CPT violation and non-standard interactions can violate this symmetry. In this work we report the measurements of and independently for neutrinos and antineutrinos. The aforementioned symmetry violation would manifest as an inconsistency in the neutrino and antineutrino oscillation parameters. The analysis discussed here uses a total of 1.9710 and 1.6310 protons on target taken with a neutrino and antineutrino beam respectively, and benefits from improved flux and cross-section models, new near detector samples and more than double the data reducing the overall uncertainty of the result. No significant deviation is observed, consistent with the standard neutrino oscillation picture
