چکیده
The one-loop contribution to the polarization operator of charged gluons in a constant Abelian chromomagnetic field at high temperature is calculated. By averaging the operator over the physical states of the transversal gluons in the field the temperature-dependent radiation corrections to the gluon energy spectrum are obtained for the high-temperature limit, gH c T 2 ≪ 1. It is found, in particular, that the radiation mass squared of charged gluons in the external field is positive in the approximation considered and has the order ∼ √ gH c T. Possible applications of the results obtained are discussed.

When chiral symmetry is spontaneously broken, the low-energy part of the Dirac operator spectrum can be computed analytically in the chiral limit. The tool is effective field theory or, equivalently in this case, Random Matrix Theory.
