Effects of nuclear medium and nonisoscalarity in extracting $sin^2\theta_W$ using Paschos-Wolfenstein relation
Abstract
We study the nuclear medium effects and nonisoscalarity correction in the extraction of weak mixing angle sin using Paschos-Wolfenstein (PW) relation. The calculations are performed for the iron nucleus. The results are discussed along with the experimental result inferred by NuTeV collaboration. The nuclear medium effects like Fermi motion, binding, shadowing and antishadowing corrections and pion and rho meson cloud contributions have been taken into account. Calculations have been performed in the local density approximation using a relativistic nuclear spectral function which includes nucleon correlations. These studies may be useful for the ongoing MINERA experiment as well as for the proposed NuSOnG experiment.
