Query: Chiral electric field in relativistic heavy-ion collisions at energies
  available at the BNL Relativistic Heavy Ion Collider and at the CERN Large
  Hadron Collider   It was proposed that the electric fields may lead to chiral separation in
QGP, which is called the chiral electric separation effect. The strong
electromagnetic field and the QCD vacuum can both completely be produced in the
off-central nuclear-nuclear collision. We used the Wood-Saxon nucleon
distribution to calculate the electric field distributions of the off-central
collisions. The chiral electro field spatial distribution at Relativistic
Heavy-Ion Collider (RHIC) and Large Hadron Collider (LHC) energy regions are
systematically studied in this paper. Compared with magnetic field spatial
distribution, electric field shows some different features in relativistic
heavy-ion collisions. The dependence of the electric field produced by the
thermal quark in the central position with different impact parameters on the
proper time with different collision energies in the RHIC and LHC energy region
are studied in this paper.
