Quasielastic Neutrino and Antineutrino Scattering Total Cross-Sections, Axial-Vector Form-Factor

Experimental results on the study of quasielastic reactions vun~#-p and ~,p--,#+n in the energy range 3-30 GeV are presented in this paper. Spark chamber detector with A1 filters has been exposed to the wide-band neutrino and antineutrino beams at Serpukhov. Neutrino and antineutrino data have been used to reconstruct the behaviour of axial-vector form-factor FA(Q2). We measured the total cross-sections as a function of energy. The parameter MA = (1.00 _+ 0.04 ) GeV/c 2 has been determined under the assumption of the dipole parametrization and CVC hypothesis. Upper limit for the second class currents was estimated.
