In quark-gluon plasma (QGP), at high temperature the spontaneous generation of colormagnetic fields, H3(T), H8(T) ≠ 0, and usual magnetic field H(T) ≠ 0 is realized. Also, the classical field –A0(T) condensate directly related to the Polyakov loop – is spontaneously created. The common generation of both within the two loop effective potential was investigated recently for SU(2) gluodynamics. The values of the field strengths and the mechanism of the magnetic fields stabilization due to A0(T) have been discovered.
In the present paper, we continue these investigations to detect new effects of QGP. We generalize the SU(2) consideration to the case of full quantum chromodynamics. Then we calculate the induced color charge Q3 ind at the background magnetic field generated at LHC experiment energies and the condensate A30(T). The field A80(T) and the charge Q8ind are zero in the used approximation.
We conclude that magnetic fields essentially influence the Q3 compared to the zero field case. The indextension to other type magnetic fields is given and a number of possible effects of this charge are briefly discussed.
