First measurement of the charged current ¯νμ double differential cross section on a water target without pions in the final state

The T2K Collaboration (K. Abe, ..., N. T. Hong Van, ...)

This paper reports the first differential measurement of the charged-current ¯νμ 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 μþ momentum and angle. The integrated cross section in a restricted phase space is σ = (1.11 +- 0.18) × 10^−38 cm2 per water molecule. Comparisons with several nuclear models are also presented.
