Duality of thermal and dynamical descriptions in particle interactions

TL;DR

This paper proposes a duality between statistical and dynamical descriptions of parton distributions in nucleons, estimating an effective temperature that aligns with freeze-out temperatures in heavy-ion collisions.

Contribution

It introduces a duality framework linking statistical and dynamical models of partons, with an estimated temperature parameter consistent across momentum dependencies.

Findings

Effective temperature close to freeze-out temperature

Temperature is similar for longitudinal and transverse momenta

Duality bridges statistical and dynamical descriptions

Abstract

We suggest a duality between the statistical and standard (dynamical) distributions of partons in the nucleons. The temperature parameter entering into the statistical form for the quark distributions is estimated. It is found that this effective temperature is practically the same for the dependence on logitudinal and transverse momenta and, it is close to the freeze-out temperature in high energy heavy-ion collisions.
