On spontaneous symmetry breaking in hot QCD

TL;DR

This paper demonstrates that in hot QCD, nontrivial vacuum states are linked to tachyonic fluctuations, leading to an improved understanding of the conditions under which these states can form.

Contribution

It establishes a connection between nontrivial vacuum states and tachyonic regimes in hot QCD, refining the criteria for their emergence.

Findings

Nontrivial vacua are associated with tachyonic fluctuations.

Improved conditions for the appearance of such states.

Enhanced understanding of hot QCD phase structure.

Abstract

We prove that nontrivial vacuum states which can arise in hot QCD are associated with the tachyonic regime of hadronic matter fluctuations. This allows us to improve the condition for such states to appear.
