Confinement Horizon and QCD Entropy

TL;DR

This paper explores the connection between quark confinement, the color event horizon, and QCD entropy, showing that lattice simulation results align with the concept of a melting horizon in the deconfined phase.

Contribution

It introduces a novel interpretation of QCD entropy in terms of a melting color event horizon, linking confinement and hadronization to horizon physics.

Findings

QCD entropy from lattice simulations matches the melting horizon model.

The color event horizon concept explains confinement and hadronization.

Entropy behavior near the critical temperature supports the horizon analogy.

Abstract

Within the picture of quark confinement as due to a \textit{color event horizon}, and of hadronization as an instance of the Unruh radiation for the strong force, we show here that QCD entropy, evaluated by lattice simulations in the region $T_c < T < 1.3 T_c$, is in reasonable agreement with a melting color event horizon.
