Abstract
This paper reports the first differential measurement of the charged-current

μ
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
+
momentum and angle. The integrated cross section in a restricted phase space is
