Determination of sin{sup 2}θ{sub W} using ν (ν{sup ¯})-nucleus scattering
Abstract
We have studied nonisoscalarity and medium effects in the extraction of weak mixing angle using Paschos and Wolfenstein relation in the iron nucleus. Paschos and Wolfenstein(PW) relation is valid for an isoscalar target. We have modified the PW relation for nonisoscalar target as well as incorporated the medium effects like Pauli blocking, Fermi motion, nuclear binding energy and pion rho cloud contributions. In our calculations we have used the relativistic nuclear spectral function which includes nucleon correlations. Finally local density approximation is applied to translate the numerical results to the finite nuclei. We have studied the dependence of sin{sup 2}θ{sub W} on Bjorken variables x and y, four momentum transfer square (Q{sup 2}), energy of the neutrino and antineutrino, and effect of excess neutrons over protons in the nuclear target.
