Non-Abelian Collective Excitations in Unlinearized Quark-Gluon Plasma Media

Abstract

We study the effect of unlinearized medium on the collective excitations in quark-gluon plasma. We present two kinds of non-Abelian oscillation solutions which respectively correspond to weakly and strongly nonlinear coupling of field components in color space. We also show that the weakly nonlinear solution is similar to Abelian-like one but has the frequency shift, which is of order $g^{2}T$, from eigenfrequency.
