  • Description: The T2K off-axis near detector, ND280, is used to make the first differential cross section measurements of muon neutrino charged current single positive pion production on a water target at energies \({\sim}0.8\) GeV. The differential measurements are presented as a function of muon and pion kinematics, in the restricted phase-space defined by \(p_{\pi^+}>200\)MeV/c, \(p_{\mu^-}>200\)MeV/c, \(\cos \theta_{\pi^+}>0.3\) and \(\cos \theta_{\mu^-}>0.3\). The total flux integrated \(\nu_\mu\) charged current single positive pion production cross section on water in the restricted phase-space is measured to be \(\langle\sigma\rangle_\phi=4.25\pm0.48 (\mathrm{stat})\pm1.56 (\mathrm{syst})\times10^{-40} \mathrm{cm}^{2}/\mathrm{nucleon}\). The total cross section is consistent with the NEUT prediction (\(5.03\times10^{-40} \mathrm{cm}^{2}/\mathrm{nucleon}\)) and 2\(\sigma\) lower than the GENIE prediction (\(7.68\times10^{-40} \mathrm{cm}^{2}/\mathrm{nucleon}\)). The differential cross sections...
