Abstract
This paper reports a measurement by the T2K experiment of the
ν
μ
charged current quasielastic (CCQE) cross section on a carbon target with the off-axis detector based on the observed distribution of muon momentum (
p
μ
) and angle with respect to the incident neutrino beam (
θ
μ
). The flux-integrated CCQE cross section was measured to be

. The energy dependence of the CCQE cross section is also reported. The axial mass,
