Contribution

It provides a detailed analysis of the statistical approach to parton distributions and compares NLO QCD predictions with experimental results, highlighting key tests at high-$x$.

Findings

Good agreement with experimental data in the high-$x$ region

Predictions support the validity of the statistical approach

Highlights the importance of specific tests for model confirmation

Abstract

We recall the physical features of the parton distributions in the quantum statistical approach of the nucleon, which allows to describe simultaneously, unpolarized and polarized Deep Inelastic Scattering data. Some predictions from a next-to-leading order QCD analysis are compared to recent experimental results and we stress the importance of some tests in the high-$x$ region, to confirm the validity of this approach.
