Abstract

Based on the Dyson-Schwinger approach, a method for obtaining the small current quark mass effect on the dressed gluon and quark propagator is developed. A comparison with the results of the previous approach is given.

Key words

Dyson-Schwinger approach / explicit and dynamical chiral symmetry breaking
