Parton distribution functions from scalar light-front parton gas model

Nuclear Theory 2025-06-12 v3

Abstract

We propose an application of a microcanonical ensemble with light-front kinematics to model the phase-space distribution of relativistic constituents of a bound state. These constituents denoted by partons are treated as classical spin-zero particles confined inside the bound state with inter-parton collisions as their only interaction. The microcanonical molecular dynamics ensemble is applied to obtain the phase-space distribution of such a thermodynamic system. We sample this phase-space distribution using Monte Carlo algorithms to obtain the parton distribution functions (PDFs) in scenarios with 33, 44, and 55 identical partons. In addition PDFs when a selected number of massless partons are mixed with 33 massive partons are also presented.
