摘要：
We have studied quasielastic charged current hyperon production induced by (nu) over bar (mu) on free nucleon and the nucleons bound inside the nucleus and the results are presented for several nuclear targets like Ar-40, Fe-56 and Pb-208. The hyperonnucleon transition form factors are determined from neutrino-nucleon scattering and semileptonic decays of neutron and hyperons using SU(3) symmetry. The nuclear medium effects(NME) due to Fermi motion and final state interaction(FSI) effect due to hyperon-nucleon scattering have been taken into account. Also we have studied two pion production at threshold induced by neutrinos off nucleon targets. The contribution of nucleon, pion, and contact terms are calculated using Lagrangian given by nonlinear sigma model. The contribution of the Roper resonance has also been taken into account. The numerical results for the cross sections are presented and compared with the experimental results from ANL and BNL.
