Nuclear medium effects in ν(ν)-nucleus deep inelastic scattering

Abstract

We study nuclear medium effects in the weak structure functions F 2(x,Q2) and F3(x,Q2) in the deep inelastic neutrino and antineutrino induced reactions in nuclei. We use a theoretical model for the nuclear spectral functions which incorporates the conventional nuclear effects, such as Fermi motion, binding, and nucleon correlations. We also consider the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. The calculations have been performed using relativistic nuclear spectral functions. Our results are compared with the experimental data of the NuTeV and the CERN Dortmund Heidelberg Saclay Warsaw (CDHSW) collaborations. © 2011 American Physical Society.
