## First measurement of the νμ charged-current cross section without pions in the final state on a water target

This data release pertains to this paper, published as Phys Rev D XXX.

## (English) Measurement of neutrino and antineutrino oscillations by the T2K experiment, including a new additional sample of electron neutrino interactions in the far detector

This data release pertains to this paper and includes results from both the frequentist and the Bayesian analyses presented there.

Both the tar files include a README document as well as several ROOT files with the results for different oscillation parameters.

For the frequentist analysis (T2K_VALOR_Data_release), each ROOT file contains the best fit point, the 68% and 90% CL contours, the χ^{2} = –2 Δln(ℒ) and Δχ^{2} map.

For the Bayesian analysis (jointfit2016_mach3.tar), each ROOT file contains the best fit point (in 2D and 4D modes), the 68% and 90% credible intervals, the 68% and 90% contours and the posterior probability density.

## Search for Lorentz and CPT violation using sidereal time dependence of neutrino flavor transitions over a short baseline

This data release pertains to this paper.

The tar file for this release is here: LVOfficialData.

This includes a README document as well as a ROOT file.

The ROOT file contains several histograms providing the distribution of neutrino events per POT with respect to the local sidereal phase for all the T2K events from run 1 to 4, for the day-only and night-only events. An additional histogram provides the result from the null hypothesis test by showing the magnitude of each sidereal mode extracted from the data by a Fast Fourier transform method. Finally, this file provide the best fit values as well as the 68% and 95% credible intervals for each SME parameter obtained by fitting the data with a binned likelihood function. Note that in this fit, the correlation between the parameters are not negligible. The two-point correlations obtained by marginalization over other parameters are also provided.

## Updated measurements of muon neutrino and antineutrino disappearance

This data release pertains to this paper.

The tar file for this data release includes a README document as well as a ROOT file.

The ROOT file contains the best fit point, the $\chi^{2}=-2 \Delta \ln \mathcal{L}$ distribution, and the contours that define the 68\% and 90\% confidence regions in the $\sin^2 \theta_{23}$ Vs $\Delta m^2_{32}$ plane. All those results correspond to the simultaneous fit of the 1 ring muon-like events recorded during neutrino and antineutrino running modes. The results are given separately for the parameters describing the disappearance of muon neutrinos and of muon antineutrinos, and are provided for the normal and inverted mass hierarchy cases.

as well as a ROOT file with the $-2 \Delta \ln \mathcal{L}$ distributions of

$\sin^2 \theta_{23}$ Vs $\Delta m^2_{32}$ ($\theta_{13}$ constrained with the PDG2015 global fit result),

$\sin^2 \theta_{13}$ Vs $\delta_{CP}$ (T2K only data) and

$\delta_{CP}$ and mass ordering ($\theta_{13}$ constrained with the PDG2015 global fit result),

Also the contours that define the 68\% and 90\% confidence regions of

$\sin^2 \theta_{23}$ Vs $\Delta m^2_{32}$ and

$\sin^2 \theta_{13}$ Vs $\delta_{CP}$ are provided.

## Neutrino beam flux prediction 2016

The files in the following archive file contain the neutrino and antineutrino beam flux predictions for the T2K ND280 (near) and Super-Kamiokande (far) detectors. It supersedes the previous flux release in 2013.

The original description of the flux predictions is published in this paper. Since the publication, the flux prediction has been updated with new thin target data from the NA61/SHINE experiment, and flux predictions for antineutrino enhanced beam operation have been produced. The NA61/SHINE thin target measurements of π^{±}, K^{±}, K_{S}^{0}, Λ and p production are published in Eur. Phys. J. C (2016) 76:84. The updated flux prediction is described in Phys. Rev. D 91, 072010 (2015).

The provided flux predictions include no neutrino oscillations.

This tar file contains the flux predictions as well as a README.pdf file with detailed information on the included files:
