Full QCD in external chromomagnetic field

TL;DR

This study explores how a constant abelian chromomagnetic field affects the deconfinement and chiral transitions in full QCD with two flavors, revealing that the critical temperatures decrease and eventually vanish as the field strength increases.

Contribution

It demonstrates the impact of an external chromomagnetic field on the phase transitions in full QCD, showing the coincidence of deconfinement and chiral transitions and their dependence on the field.

Findings

Deconfinement temperature decreases with increasing chromomagnetic field.

Chiral transition coincides with deconfinement transition.

Chiral condensate increases as the chromomagnetic field strength grows.

Abstract

We investigate the deconfining phase transition in full QCD with two flavors of staggered fermions in presence of a constant abelian chromomagnetic field. We find that the deconfinement temperature decreases and eventually goes to zero by increasing the strength of the chromomagnetic field. Moreover our results suggest that the chiral transition coincides with the deconfinement transition and therefore even the chiral critical temperature depends on the applied chromomagnetic field. We also find that the chiral condensate increases with the strength of the chromomagnetic field.
