The Quantum Statistical Approach to Parton Distributions updated with recent experimental data

Year: 2026

Type: preprint

Abstract: The Quantum Statistical Parton Model (QSPM) has been successful over the years to explain a important set of unpolarized and polarized experimental data on proton parton distribution functions (PDFs). With the advent of the Marathon and SeaQuest experiments, an updated version of the quark PDFs obtained in the framework of QSPM is presented. Moreover, in order to clarify the role of the thermodynamical potentials, the main parameters of the model, we examine the dependence of the nucleon entropy on these potentials. We find that the values of these potentials lead to a maximal value for the nucleon entropy.
