The Sea in the Nucleon

摘要: The meson-exchange model, as proposed recently by Hwang, Speth, and Brown in generalizing the Sullivan process to account for sea distributions of a free nucleon at moderate Q^2 (e.g., up 20 GeV^2), is described. form factors associated with couplings mesons baryons such πNN, πNΔ, KNΛ are constrained CCFR neutrino data. model then yields predictions consistent CDHS Fermilab E615 It also found that recent finding New Muon Collaboration (NMC) on violation Gottfried sum rule can be understood quantitatively.
