Abstract
Minkowski structure of the Fermion propagator in QED is evaluated using dispersion like method Including massive fermion loop to the photon spectral function there is no infrared divergences in the gauge d=-1.Screening effects suppress the chiral order parmeter for small numbers of fermion flavour N.We evaluate the order parameter as a function of coupling constant c and N.There exsists a critical region where the chiral symmetry is dynamically broken.
