We report the measurements of the single and double differential cross section of muon neutrino charged-current interactions on carbon with a single positively charged pion in the final state at the T2K off-axis near detector using 5.56\ifmmode\times\else\texttimes\fi{}{10}^{20}protons on target. The analysis uses data control samples for the background subtraction and the cross section signal, defined as a single negatively charged muon and...
