A global next-to-leading order QCD analysis of unpolarized and polarized deepinelastic scattering data is performed with parton distributions constructed in a statistical physical picture of the nucleon. The chiral properties of QCD lead to strong relations between quarks and antiquarks distributions and the importance of the Pauli exclusion principle is also emphasized. We obtain a good description, in a broad range of x and Q 2 , of all measured structure functions in terms of very few free parameters.We stress the fact that at RHIC-BNL the ratio of the unpolarized cross sections for the production of W + and W − in pp collisions, will directly probe the behavior of the d(x)/u(x) ratio for x ≥ 0.2, a definite and important test for the statistical model. Finally, we give specific predictions for various helicity asymmetries for the W ± , Z production in pp collisions at high energies, which will be measured with forthcoming experiments at RHIC-BNL and are sensitive tests of the statistical model for ∆u (x) and ∆d(x).

Target mass corrections and higher twist effects in polarized deep-inelastic scattering

We perform a next-to-leading-order QCD analysis to world data on polarized structure functions g1 and g2 in a fixed-flavor number scheme. We include target mass corrections and higher twist effects in our fitting procedure and study their non-negligible effects on physically interesting quantities. Twist-3 contributions to both polarized structure functions are determined, and the accuracy of the extracted polarized parton distribution functions is improved. 3 He and 3 H polarized structure functions are described based on our fit result. Moreover, sum rules are derived and compared with available theoretical and experimental results.
