Fermion and photon gap-equations in Minkowski space within the Nakanishi integral representation method
Abstract The approach based on the Nakanishi integral representation of n-leg transition amplitudes is extended to the treatment of the self-energies of a fermion and an (IR-regulated) vector boson, in order to pave the way for constructing a comprehensive application of the technique to both gap- a...
