The Polyakov-Nambu-Jona-Lasinio model with six and eight quark interactions

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.Comment: 3 pages, 6 figures, to appear in the conference proceedings for Quark Confinement and the Hadron Spectrum IX, August 30- September 3 2010, Madrid (Spain
