Quasielastic neutrino and antineutrino scattering total cross-sections, axial-vector form-factor

Experimental results on the study of quasielastic reactions νsub(μ)n->μ-p and anti νsub(u)p->μ+n in the energy range 3-30 GeV are presented in this paper. Spark chamber detector with Al 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 Fsub(A)(Q2). We measured the total cross-sections as a function of energy. The parameter Msub(A)=(1.00+-0.04) GeV/c2 has been determined under the assumption of the dipole parametrization and CVC hypothesis. Upper limit for the second class currents was estimated. (orig.)
