Comment on the dressed Polyakov loop in the Nambu--Jona-Lasinio model [PDF]
Sanjin BenićWe argue that in spite of the fact that the dressed Polyakov loop in the Nambu--Jona-Lasinio (NJL) model shows a rapid change as a function of the temperature, this should not be interpreted as a confinement-deconfinement phase transition. In particular, it certainly does not mean that the NJL model itself is confining. Rather, we show that this behaviour is simply a remnant of the chiral transition.View original: http://arxiv.org/abs/1305.6567
