The Fermi excitations in hot and dense quark–gluon plasma are studied in the Feynman gauge using the temperature Green function technique. We find four well-separated spectrum branches for all |q| in the case m=0 and establish the additional splitting between them (four different effective masses) when m≠0. The long wavelength limit of these excitations is found in the general case of the massive fermions at finite temperature and baryon densities to give the exact one-loop spectrum. This spectrum exhibits many known results as its different limits.
