Chemical Potential Dependence of the Dressed-Quark Propagator in a Simple Confining QCD Model
-
Abstract
Based on the Dyson-Schwinger approach, a method for obtaining the chemical potential dependence of the dressed quark propagator in the ‘Nambu-Goldstone’ and the ‘Wigner’ phase is developed. The bag constant in the presence of the non-zero chemical potential is analysed.
