We study the influence of external parallel electric and magnetic fields and a chiral chemical potential mu(5) on the chiral phase transition of quantum chromodynamics. Our theoretical framework is a Nambu-Jona-Lasinio model with a contact interaction. Within this model we compute the critical temperature of chiral symmetry restoration T-c as a function of the chiral chemical potential and field strengths. We find that the fields inhibit and mu(5) enhances chiral symmetry breaking, in agreement with previous studies.

Abstract
We study the influence of external parallel electric and magnetic fields and a chiral chemical potential mu(5) on the chiral phase transition of quantum chromodynamics. Our theoretical framework is a Nambu-Jona-Lasinio model with a contact interaction. Within this model we compute the critical temperature of chiral symmetry restoration T-c as a function of the chiral chemical potential and field strengths. We find that the fields inhibit and mu(5) enhances chiral symmetry breaking, in agreement with previous studies.File in questo prodotto:
