Q-ball formation at the deconfinement temperature in large-Nc QCD
23 janvier 2013, HE Louvain en HainautArticle scientifiqueThe 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 ...
