Abstract
We study the effects of density-dependent electromagnetic, axial, and weak vector form factors on the inclusive reaction and the charged-current neutrino-nucleus scattering in the quasi-elastic region within the framework of a relativistic single-particle model. The density-dependent form factors obtained from a quark-meson coupling model are applied into the reaction and the neutrino-nucleus scattering via charged current. The effects of the density-dependent form factors increase the cross sections by a few percent. However, the effects may reduce the differential cross sections up to 20% (60%) at for the antineutrino scattering and also reduce the cross section up to 20% (30%) at for the neutrino scattering around the peak positions, where the normal density is . For the density of finite nuclei such as , , and as 0.6, 0.7, and 1.0 of , the in-medium effects are 20% to 30%, even in the antineutrino case. Our theoretical double-differential and total cross sections are compared with the recent MiniBooNE data for scattering.
