- Аннотация: The one-loop radiative correction to the quark energy in an external gauge field has been calculated within a (2 + 1)-dimensional QCD model without taking into account the Chern-Simons topological term. By using the proper-time formalism, the propagators of quarks and gluons in external chromomagnetic and chromoelectric fields have been found in the coordinate representation. The asymptotic expression for the radiative correction to the quark energy have been obtained for the case of weak fields. Infrared divergence of the resulting expressions has been investigated, and a finite gluon mass has been introduced to remove this divergence. It has been shown that, in contrast to what occurs in (3 + 1)-dimensional QCD, the radiative shift of the quark energy is real-valued.
