Burkardt, M

Based on a simple K-cloud model, as well as the Gross-Neveu and the Nambu-Jona-Lasinio model, it is predicted that the s{bar s} sea in a proton is not charge symmetric at large Bjorken-x. The s quarks are shifted to larger values of x{sub bj} than the {bar s} quarks. Furthermore these large x{sub bj} s quarks carry a negative polarization. 9 refs., 2 figs.
