1209.0589 (Marco Ruggieri et al.)

Quasiparticles and $Z(N)-$ lines in Hot Yang-Mills theories    [PDF]

Marco Ruggieri, Paolo Alba, Paolo Castorina, Salvatore Plumari, Claudia Ratti, Vincenzo Greco
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.
