Klimov, V

A new method is proposed for finding the dispersion laws of collective excitations in systems described by non-Abelian gauge theories. The method is based on an expansion of the polarization and mass operators at high temperatures. By means of the method, the dispersion laws of collective Bose and Fermi excitations in a hot quark-gluon plasma are found explicitly. Without being inconsistent with the gauge and chiral symmetries, all the dispersion laws have an optical nature. Possible experimental consequences of the obtained results are briefly discussed.
