Recent results in the Statistical Approach of Polarized PDF and Extension to Baryon Fragmentation Functions
Jacques Soffer
Abstract
Parton distributions are 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. A global next-to-leading order QCD analysis of unpolarized and polarized deep-inelastic scattering data is performed to determine a small number of free parameters. Some predictions are compared to recent experimental results. We also present an extension of the statistical approach to the description of baryon fragmentation functions.
