QCD dynamics in a constant chromomagnetic field

TL;DR

This paper studies how a constant chromomagnetic field affects the phase transition in full QCD with two flavors, revealing that the critical temperature decreases with field strength and the deconfined phase appears at lower temperatures.

Contribution

It demonstrates the impact of a constant chromomagnetic field on QCD phase transitions, showing the dependence of critical temperature and chiral condensate on field strength.

Findings

Critical temperature decreases as chromomagnetic field strength increases.

Deconfined phase extends to lower temperatures under strong fields.

Chiral condensate increases with field strength.

Abstract

We investigate the phase transition in full QCD with two flavors of staggered fermions in presence of a constant abelian chromomagnetic field. We find that the critical temperature depends on the strength of the chromomagnetic field and that the deconfined phase extends to very low temperatures for strong enough fields. As in the case of zero external field, a single transition is detected, within statistical uncertainties, where both deconfinement and chiral symmetry restoration take place. We also find that the chiral condensate increases with the strength of the chromomagnetic field.
