Radiative Shift of the Quark Mass in a Constant Chromomagnetic Field at Finite Temperature and Density
Abstract
The radiation shift of the quark mass in a constant chromomagnetic field at finite temperature and density was calculated. The limiting cases of a weak and a strong chromomagnetic field were considered. It was shown that in a strong field there is no imaginary part in the contribution of the finite density effects to the quark mass shift, and its real part can considerably exceed the corresponding part of the purely field contribution.
