First measurement of the charged current (nu)over-bar(mu) double differential cross section on a water target without( )pions in the final state. Phys. Rev. D, 102(1), 012007–16pp.
Abstract: This paper reports the first differential measurement of the charged-current (nu) over bar (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 = (1.11 +/- 0.18) x 10(-38) cm(2) per water molecule. Comparisons with several nuclear models are also presented.
