Confinement bubble wall velocity via quasiparticle determination
Abstract Lattice simulations reveal that the deconfinement-confinement phase transition (PT) of the hot pure SU(N > 2) Yang-Mills system is first order. This system can be described by a pool of quasigluons moving in the Polyakov loop background, and in this picture, we establish an effective dis...

| description | Abstract Lattice simulations reveal that the deconfinement-confinement phase transition (PT) of the hot pure SU(N > 2) Yang-Mills system is first order. This system can be described by a pool of quasigluons moving in the Polyakov loop background, and in this picture, we establish an effective distribution function for quasigluons, which encodes interactions among quasigluons and in particular the confinement effect. With it, we made the first attempt to calculate the confinement bubble wall velocity v w at the microscopical level, and we obtained a small velocity v w ~ 0.04 using two different approaches, which is qualitatively consistent with others results like holography. |
