Induced Color Charges, Effective γγG Vertex in QGP. Applications to Heavy-Ion Collisions
We calculate the induced color charges Q3ind,Q8ind and the effective vertex y−y-gluon generated in a quark-gluon plasma with the A0 condensate because of the color C-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 ¯ ф3 and ¯ ф8 produced by these charges. Two applications – the scattering of photons on a plasma and the conversion of gluon fields in two photons radiated from the plasma – are discussed.
