Abstract:Based on the Dyson-Schwinger Equations (DSEs) of QCD in the "rainbow" approximation, the fully dressed quark propagator S f ( p) is investigated, and then an algebraic parametrization form of the propagator is obtained as a solution of the equations. The dressed quark amplitudes A f and B f which built up the fully dressed quark propagator, and the dynamical running masses M f , which is defined by A f and B f for light quarks u, d and s, are calculated, respectively. Using the predicted current masses m f , q… Show more
