Entropy Production During Hadronization of a Quark-Gluon Plasma

TL;DR

This paper examines entropy production during quark-gluon plasma hadronization, proposing a new perspective on resonance spectra and non-equilibrium mechanisms to address entropy changes.

Contribution

It introduces a novel approach to entropy production, challenging the infinite resonance tower assumption and exploring stochastic dynamics in hadronization.

Findings

Entropy production can occur without an infinite resonance spectrum.

A new model for non-equilibrium entropy generation during hadronization.

Insights into the role of stochastic processes in QGP evolution.

Abstract

We revisit the physical pictures for the hadronization of quark-gluon plasma, concentrating on the problem of entropy production during processes where the number of degrees of freedom is seemingly reduced due to color confinement. Based on observations on Regge trajectories we propose not having an infinite tower of hadronic resonances. We discuss possible entropy production mechanisms far from equilibrium in terms of stochastic dynamics.
