Description
An important tool to deal with the formulation in Minkowski space is the Integral
Representation (IR) proposed by Nakanishi.
In this work, we use the IR to obtain a solution of the Dyson-Schwinger equation directly in Minkowski space, and compare with a solution in a rotated axis from the Euclidean axis, what we call ``Un-Wick rotation''. To this end we must find the relation between the fermion propagator self energy and the spectral densities, together with the DSE in the rainbow-approximation.
We solve the DSE in the rainbow ladder approximation for massive gauge boson, written for the spectral densities in arbitrary gauges with undressed gauge-boson-fermion vertex in the Minkowski space by using the Nakanishi Integral Representation.
