Effect due to charge symmetry violation on the Paschos-Wolfenstein relation
The modification of the Paschos-Wolfenstein relation is investigated when the charge symmetry violations of valence and sea quark distributions in the nucleon are taken into account. We also study qualitatively the impact of charge symmetry violation (CSV) effect on the extraction of ${sin}^{2}{\ensuremath{\theta}}_{w}$ from deep-inelastic neutrino- and antineutrino-nuclei scattering within …
