Perturbation theory
Dressed perturbation theory for the quark propagator: Fernando Enrique Serna Algarín. -
... termined self-consistently from Eqs. (5.17) and (5.20). Now, if one takes, e.g. both zeroth order self-energies from fits to lattice data or other approximation schemes, it should be clear that Eqs. (5.17) and (5.20) ...
