Effects of density-dependent weak form factors on neutral-current neutrino (antineutrino)-neucleus scattering in the quasi-elastic region

Abstract

We study the effects of density-dependent weak vector form factors on the inclusive neutral-current--neutrino (antineutrino)-nucleus scattering in the quasi-elastic region within the framework of a relativistic single-particle model. The density-dependent weak form factors are obtained from a quark-meson coupling model. The density-dependence effects are studied separately in protons and neutrons participating in the reactions, in each response cross section, and with regard to asymmetry. These density effects reduce the cross section at high densities and show different behavior with regard to asymmetry. Furthermore we calculate flux-averaged differential cross sections and compare them with the experimental data.
