Recent status of the understanding of neutrino-nucleus cross section

In this work we have presented current understanding of neutrino-nucleon/nucleus cross sections in the few GeV energy region relevant for a precise determination of neutrino oscillation parameters and CP violation in the leptonic sector. In this energy region various processes like quasielastic and inelastic production of single and multipion production, coherent pion production, kaon, eta, hyperon production, associated particle production as well as deep inelastic scattering processes contribute to the neutrino event rates.Comment: 9-Pages, 4-figures, Talk given at DAE-HEP Symposium held at Delhi University, 12-16 December, 201

Effects of nuclear medium and nonisoscalarity in extracting sin2θWsin^2\theta_W using Paschos-Wolfenstein relation

We study the nuclear medium effects and nonisoscalarity correction in the extraction of weak mixing angle sin$^2\theta_W$ 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 MINER$\nu$A experiment as well as for the proposed NuSOnG experiment.Comment: 31 pages, 6 figures. Accepted version to be published in Phys. Rev.
