Anti-Pauli blocking in QCD1+1

We investigate the flavor asymmetry of the q bar q sea in a (uu)-proton for QCD1+1 with SU(2)-color. The excess of bar u over bar d which apparently seems to be in conflict with the exclusion principle is explained by taking the color degrees of freedom into account. By computing color factors for the relevant perturbation theory diagrams we show that the non-abelian sea quarks behave effectively similar to abelian bosons. For the magnitude of the flavor asymmetry of the sea we predict scaling proportional to the ratio of the quark Compton wavelength to the proton radius. We show that the sign of the asymmetry in QCD1+1 is different from the sign measured in 3+1 dimensions. 9 refs., 1 fig., 1 tab
