First Measurement of the Charged Current \(\overline{\nu}_{\mu}\) Double Differential Cross Section on a Water Target without Pions in the final state

This paper reports the first differential measurement of the charged-current \(\overline{\nu}_{\mu}\) 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 \(\mu^+\) mom...

Description
Summary:This paper reports the first differential measurement of the charged-current \(\overline{\nu}_{\mu}\) 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 \(\mu^+\) momentum and angle. The integrated cross section in a restricted phase space is \(\sigma=\left(1.11\pm0.18\right)\times10^{-38}\) cm\(^{2}\) per water molecule. Comparisons with several nuclear models are also presented.
