AbstractBased on the Dyson-Schwinger equations 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 built up the fully dressed quark propagator and the dynamical running masses M-f defined by A(f) and B-f for light quarks u, d and s are calculated, respectively. Using the predicted running masses M-f, quark condensates <0\q(0)q(0)\0> = -(0.255 GeV)(3) for u, d quarks, and <0\(s) over bars\0> = 0.8(0\(q) over bar (0)q(0)\0) for s quark, and experimental pion decay constant f(pi) = 0.093 GeV, the masses of Goldstone bosons K, pi, and eta are also evaluated. The numerical results show that the masses of quarks are dependent on their momentum p(2). The fully dressed quark amplitudes Af and Bf have correct behaviors which can be used for many purposes in our future researches on nonperturbative QCD.
