Abstract
We study the competition of quark-antiquark and diquark condensates under the influence of an external chromomagnetic field modeling the gluon condensate and its dependence on the chemical potential and temperature. As our results indicate, an external chromomagnetic field might produce remarkable qualitative changes in the picture of the color superconducting (CSC) phase formation. This concerns, in particular, the possibility of a transition to the CSC phase and diquark condensation at finite temperature.
