The Flavor Asymmetry of the Nucleon Sea

  title={The Flavor Asymmetry of the Nucleon Sea},
  author={Fernanda Steffens and Anthony W. Thomas},
We reexamine 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.
