Flavor Asymmetry in Hyperons and Drell-Yan Processes

Nuclear Theory 2009-09-25 v1

Abstract

SU(3), baryon octets and a meson cloud model are compared for the flavor asymmetry of sea quarks in the Σ+\Sigma^+, as an example. Large differences are found, especially between SU(3) and the meson cloud model. We suggest Drell-Yan measurements of Σ+p\Sigma^{+}-p and Σ+d\Sigma^{+}- d to test the prediction of various models. We use the meson cloud model to predict both valence and sea quark distributions.
