摘要

The nucleon weak axial-vector form factor for quasielastic interactions is determined from the analysis of neutrino-Carbon interactions in the K2K detector fully active SciBar tracking calorimeter. The analysis consists on a fit to the four-momentum squared, Q2 = ?q2 = (Pμ?P)2, of the quasi elastic reaction μnμ?p, induced by the neutrino interactions on the Carbon nuclei. The axial-vector form factor can be approximated by a dipole with the axial-vector mass as a free parameter, with a best fit for MA = 1.144±0.077(fit)(syst).
