Induced color charges, effective gamma-gamma-gluon vertex in QGP. Applications to heavy-ion collisions
Abstract
We calculate the induced color charges Qind.3, Qind.8 and the effective vertex gamma - gamma - gluon generated in quark-gluon plasma with the A0 condensate because of the color parity violation at this background. To imitate the case of heavy-ion collisions, we consider the model of the plasma confined in the narrow infinite plate and derive the classical gluon potentials Phi3, Phi8 produced by these charges. Two applications - scattering of photons on the plasma and conversion of gluon fields in two photons radiated from the plasma - are discussed.
