Abstract
We have studied the muon neutrino and antineutrino quasi-elastic (QEL) scattering reactions (I1/2 .sub.u n[right arrow]u .sup.- p and [nu] .sub.[mu].sup.+n ) using a set of experimental data collected by the NOMAD Collaboration. We have performed measurements of the cross-section of these processes on a nuclear target (mainly carbon) normalizing it to the total I1/2 .sub.u ( [nu].sub.[mu] ) charged-current cross section. The results for the flux-averaged QEL cross sections in the (anti)neutrino energy interval 3--100 GeV are [sigma].sub.qel.sub.[nu].sub.[mu]=(0.92\pm0.02(stat)\pm0.06(syst))\times10.sup.-38~cm.sup.2 and [sigma].sub.qel.sub.[nu].sub.[mu]=(0.81\pm0.05(stat)\pm0.09(syst))\times10.sup.-38~cm.sup.2 for neutrino and antineutrino, respectively. The axial mass parameter M .sub.A was extracted from the measured quasi-elastic neutrino cross section. The corresponding result is M .sub.A=1.05+-0.02(stat)+-0.06(syst) GeV. It is consistent with the axial mass values recalculated from the antineutrino cross section and extracted from the pure Q .sup.2 shape analysis of the high purity sample of I1/2 .sub.u quasi-elastic 2-track events, but has smaller systematic error and should be quoted as the main result of this work. Our measured M .sub.A is found to be in good agreement with the world average value obtained in previous deuterium filled bubble chamber experiments. The NOMAD measurement of M .sub.A is lower than those recently published by K2K and MiniBooNE Collaborations. However, within the large errors quoted by these experiments on M .sub.A, these results are compatible with the more precise NOMAD value.
