Chiral medium produced by parallel electric and magnetic fields

Résumé

We compute (pseudo)critical temperature, Tc, of chiral symmetry restoration for quark matter in the background of parallel electric and magnetic fields. This field configuration leads to the production of a chiral medium on a time scale τ, characterized by a nonvanishing value of the chiral density that equilibrates due to microscopic processes in the thermal bath. We estimate the relaxation time τ to be about ≈0.1−1 fm/c around the chiral crossover; then we compute the effect of the fields and of the chiral medium at the crossover. We find Tc to be lowered by the external fields in the chiral medium.
