The Flavor Asymmetry of the Nucleon Sea

arXiv:nucl-th/9612056 · doi:10.1103/PhysRevC.55.900

Abstract

We re-examine the effects of anti-symmetry on the anti-quarks in the nucleon sea arising from gluon exchange and pion exchange between confined quarks. While the effect is primarily to suppress anti-down relative to anti-up quarks, this is numerically insignificant for the pion terms.
