Abstract

The NuTeV Collaboration recently reported a value of (Formula presented) measured in neutrino-nucleon scattering that is 3 standard deviations above the standard model prediction. This result is derived assuming that (1) the strange sea is quark-antiquark symmetric, (Formula presented) and (2) up and down quark distributions are symmetric under the simultaneous interchange of (Formula presented) and (Formula presented) We report the impact of violations of these symmetries on (Formula presented) and discuss the theoretical and experimental constraints on such asymmetries. © 2002 The American Physical Society.
