      The deconfinement phase transition in large-Nc QCD is studied within the framework of an effective Polyakov-loop model, where the potential has a U(1) symmetry originating in the large-Nc limit of a ZNc-symmetric model. At the critical temperature, the shape of the effective potential allows the existence of Q-balls as position-dependent fluctuations of the Polyakov loop. Q-balls with spherical ...

    • Thermodynamics of the quark-gluon plasma within a T-matrix approachPeer reviewedOpen access 

      24 juin 2015, Lacroix, Gwendolyn; Semay, Claude; BUISSERET, Fabien, HE Louvain en Hainaut
      Article scientifique
      The strongly coupled phase of the quark-gluon plasma (QGP) is studied here by resorting to a T -matrix formulation in which the medium is seen as a nonideal gas of quasiparticles (quarks, antiquarks, and gluons) interacting nonpertubatively. In the temperature range under study, (1–5)Tc, where Tc is the temperature of deconfinement, the interactions are expected to be strong enough to generate ...
