Abstract

This paper reports the first differential measurement of the charged-current ν‾μ\overline{\nu}_{\mu} interaction cross section on water with no pions in the final state. The unfolded flux-averaged measurement using the T2K off-axis near detector is given in double differential bins of μ+\mu^+ momentum and angle. The integrated cross section in a restricted phase space is σ=(1.11±0.18)×10−38\sigma=\left(1.11\pm0.18\right)\times10^{-38} cm2^{2} per water molecule. Comparisons with several nuclear models are also presented.
