It is shown, that specific chirality and flavor properties of the instanton-induced interaction allow us to explain the observed violation Ellis-Jaffe and Gottfried sum rules. A large value of these violations originates from the anomalous growth of the instanton-induced interaction between quarks at high energy. The new sum rule which connect the values of violations of Ellis-Jaffe and Gottfri...

The Vanishing Tradition, dirige par Paul Gottfried, universitaire et paleoconservateur, s’ouvre a la fois sur un constat objectif : le mouvement conservateur americain produit sa propre histoire, qui « s’eloigne de realite factuelle » ; il s’agit donc remettre celle-ci en question. L’originalite l’ouvrage provient toutefois du fait que, comme remarquer Gottfried introduction, « la plupart des c...

We investigate the non-perturbative effect in the nucleon structure function and the Gottfried sum by using a non-perturbative quark propagator with lowest dimensional condensate contributions from the QCD vacuum. It is shown that the non-perturbative effect modifies the conventional quarkparton model formula of the nucleon structure function at finite Q2 and suggests a non-trivial Q2 dependenc...

The sensitivity of W and Z production at RHIC to the possible ū/d̄ asymmetry in the proton is studied. The ratios of the W over W production cross sections in p+ p collision, as well as the ratios of the W and Z production cross sections for p + p over p + d collisions, are shown to be sensitive to this asymmetry. Predictions of various theoretical models for these ratios are presented. The vali...

We study shadowing and antishadowing corrections to the flavor nonsinglet structure function F 3He 2 − F 3H 2 and show that the difference between the one-particle density distributions of 3He and 3H plays an important role at very small x. We find that the flavor non-singlet structure function in these mirror nuclei is enhanced at small x by nuclear shadowing, which increases the nuclear Gottf...
