High intensity monoenergetic muon neutrinos of energy 236 MeV from the kaon decay at rest at the medium energy proton accelerator facilities like J-PARC and Fermilab are proposed to be used for making precision measurements of neutrino-nucleus cross sections in and and perform neutrino oscillation experiments in and modes. In view of these developments, we study the theoretical uncertainties arising due to the nuclear medium effects in the neutrino-nucleus cross sections as well as in the angular and energy distributions of the charged leptons produced in the charged current induced reactions by and in and in the energy region of MeV. The calculations have been done in a microscopic model using the local density approximation which takes into account the nuclear effects due to the Fermi motion, binding energy and long range correlations. The results are compared with the other calculations available in the literature. [ABSTRACT FROM AUTHOR]

We study the nuclear medium effects in Drell–Yan process using quark parton distribution functions calculated in a microscopic nuclear model which takes into account the effects of Fermi motion, nuclear binding and nucleon correlations through a relativistic nucleon spectral function. The contributions of π and ρ mesons as well as shadowing effects are also included. The beam energy loss is calculated using a phenomenological approach. The present theoretical results are compared with the experimental results of the E772 and E866 experiments. These results are applicable to the forthcoming experimental analysis of E906 Sea Quest experiment at the Fermi Lab. [ABSTRACT FROM AUTHOR]

We have studied quasielastic charged current hyperon production induced by from a free nucleon and the nucleons bound inside the nucleus. The calculations are performed for several nuclear targets, for example 12C, 40Ar, 56Fe and 208Pb, which are currently being used in various oscillation experiments using accelerator neutrinos. The inputs are the hyperon–nucleon transition form factors determined from neutrino–nucleon scattering as well as from semileptonic decays of neutron and hyperons, using SU(3) symmetry. The calculations for the nuclear targets are done using the local density approximation. The nuclear medium effects due to the Fermi motion and Pauli blocking, and the final state interaction effects due to hyperon–nucleon scattering have been taken into account. [ABSTRACT FROM AUTHOR]
