| Abstract: | The cross sections of neutrino and antineutrino quasielastic reactions (vn to mu ^ - p,bar vp to mu ^ + n,bar vp to mu ^ + Lambda) were studied in the neutrino energy range between 3 and 30 GeV. In comparison withV-A theory axial mass parameters ofM A =(1.06±0.05±0.14) GeV/c2 from neutrino andM A =(0.71±0.10±0.20) GeV/c2 from antineutrino data were found. The total cross-section for the hyperon production process can be described byM A =1.0 GeV/c2. |
