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

June 28, 2017

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.
