Abstract
A recent experiment by the NuTeV collaboration resulted in a surprisingly high value for the weak mixing angle . The Paschos-Wolfenstein relation, relating neutrino cross sections to the Weinberg angle, is of pivotal importance in the NuTeV analysis. In this work, we investigate the sensitivity of the Paschos-Wolfenstein relation to nuclear structure aspects at neutrino energies in the few GeV range. Neutrino-nucleus cross sections are calculated for O and Fe target nuclei within a relativistic quasi-elastic nucleon-knockout model.
