The Polyakov-Nambu-Jona-Lasinio model with six and eight quark interactions
arXiv:1011.5490 · doi:10.1063/1.3575028
Abstract
The extension of the Nambu-Jona-Lasino Model with six and eight quark interactions to include the Polyakov loop is analysed. Several interesting features are determined to be an effect of the choice of the regularization procedure. The use of a Pauli-Villars covariant regularization enables a coherent and correct description of several quantities.
