Here we present a self-consistent quasiparticle model for quark-gluon plasma (QGP) and apply it to explain the nonideal behavior seen in lattice simulations. The basic idea, borrowed from electrodynamic plasma, is that the gluons acquire mass as they propagate through plasma due to collective effect ... [Phys. Rev.
