Quasiparticles and $Z(N)-$ lines in Hot Yang-Mills theories
arXiv:1209.0589 · doi:10.1063/1.4763531
Abstract
In this talk we review, the quasiparticle description of the hot Yang-Mills theories, in which the quasiparticles propagate in (and interact with) a background field related to Z(N)-lines. We compare the present description with a more common one in which the effects of the Z(N)-lines are neglected. We show that it is possible to take into account the nonperturbative effects at the confinement transition temperature even without a divergent quasiparticle mass.
