On the s-sbar asymmetry of the nucleon sea
Abstract
We study the s- s asymmetry in the nucleon sea using a model in which the proton wave function includes a Kaon-Hyperon Fock state. Parameters of the model are fixed by fitting the s- s asymmetry obtained from global fits to Deep Inelastic Scattering data. We discuss possible effects of the s- s asymmetry on the measurement of the Weinberg angle by the NuTeV Collaboration.
