Zong Hong-Shi, Wu Xiao-Hua, Sun Weimin, En-Guang Zhao, Fan Wang

Abstract

A method for obtaining the small current quark mass dependence of the dressed quark propagator from an effective quark-quark interaction model is developed. Within this approach the small current quark mass effects on dressed-quark propagator have been studied. A comparison with previous results is given.
