The quark-gluon plasma is a novel state of matter in which quarks are no longer confined to bound
states such as baryons and mesons. the freezing of quark–gluon deconfined degrees of freedom is the
essential ingredient in determining the conditions in a transition between phases that has time to
develop into equilibrium. The degree of freedom in the confined hadronic matter phase and the
deconfined phase, that is, the QGP, is important in the study of phase transition in the early universe. It
is calculated according to the strong coupling constant. But in the present work, we try to figure out the
effect of the running coupling constant in the calculation of the degree of freedom, the latent heat and
the critical pressure in the confined-deconfined phase of matter. |
