Data release for the "First double-differential measurement of pionless charged-current muon neutrino interactions using kinematic imbalance observables on carbon and oxygen with the T2K experiment"
T2K first double-differential pionless CC νμ measurement: data release
AbstractThis data release provides the results regarding the cross-section measurement of pionless charged-current muon neutrino interactions with kinematic imbalance observables on carbon and oxygen using data from the ND280 detector of the T2K experiment. The release consists of the differential cross-section results, the covariance matrices of the cross-section results and the best-fit T2K neutrino fluxes in CSV files. For full details, please read README.txt which is included in the release and copied below.README.txtThis data release for the numuCC0piNp cross-section measurement with kinematic imbalance observables on carbon and oxygen by the T2K experiment.
The release contains following results:
Differential cross-section results.
– The results in dpt-dalphat space are included in "xseccarbondptdalphat.csv" and "xsecoxygendptdalphat.csv" for carbon and oxygen targets respectively. 2D bin information is included as well. The cross-section is shown in the unit of "d^2sigma / (dpt dalphat) [cm^2 / (degree * GeV/c * nucleon)]".
– The results in pn-costhetamu space are included in "xseccarbonpncosthetamu.csv" and "xsecoxygenpncosthetamu.csv" for carbon and oxygen targets respectively. 2D bin information is included as well. The cross-section is shown in the unit of "d^2sigma / (dpn dcosthetamu) [cm^2 / (GeV/c * nucleon)]".
Covariance matrices of cross-section results.
– The covariance matrix in dpt-dalphat space is included in …
