Özet

The thermodynamic potential of quark-gluon plasma is investigated in the lightcone gauge. In this gauge, the gluon propagator has unphysical poles of kind 1/(n · k). In order to remove these singularities Mandelstam and Leibbrandt have proposed a new prescription. In this work the thermodynamic potential of quark-gluon plasma is calculated at two-loop approximation using the Mandelstam-Leibbrandt prescription and the obtained expression is shown to be gauge invariant.
