摘要: Valence u- and d-quark distributions in nucleon and pion at small x (x = -q exp 2 /2nu is the fraction of the momentum carried by quarks) corresponding to rho and omega Regge pole exchange have been obtained on the basis of the QC... 展开 Valence u- and d-quark distributions in nucleon and pion at small x (x = -q exp 2 /2nu is the fraction of the momentum carried by quarks) corresponding to rho and omega Regge pole exchange have been obtained on the basis of the QCD sum rule method. 6 references, 3 figures.
