Deep Inelastic Neutrino Interactions

oscillation hypothesis will be tested through ντ production of τ in long-baseline experiments as well as underground neutrino telescopes. An anomaly in the deep inelastic interaction of neutrinos has recently been observed by the NuTeV collaboration – resulting in a measured weak mixing angle sin ΘW that differs by ∼ 3σ from the standard model expectation. In this contribution to the proceedings of NUINT02, we summarize results on the NLO neutrino structure functions and cross sections in which charm quark mass and target mass effects in the collinear approximation are included.
