Abstract

The Charged-Current Quasi-Elastic (CCQE) interaction, νl + n → l − + p, is the dominant CC process at Eν ∼ 1 GeV and contributes to the signal in accelerator-based long-baseline neutrino oscillation experiments operating at intermediate neutrino energies. This paper reports a measurement by the T2K experiment of the νµ CCQE cross section on a carbon target with the off-axis detector based on the observed distribution of muon momentum (pµ) and angle with respect to the incident neutrino beam (θµ). The flux-integrated CCQE cross section was measured to be hσi = (0.83 ± 0.12) × 10−38 cm2 . The energy dependence of the CCQE cross section is also reported. The axial mass, MQE A , of the dipole axial form factor was extracted assuming the Smith-Moniz CCQE model with a relativistic Fermi gas nuclear model. Using the absolute (shapeonly) pµ-cosθµ distribution, the effective M QE A parameter was measured to be 1.26+0.21 −0.18 GeV/c2 (1.43+0.28 −0.22 GeV/c2 ).
