Analytical solution for the correlator with Gribov propagators
Original language description
Propagators approximated by meromorphic functions with complex conjugated poles are widely used to model the infrared behavior of QCD Green's functions. In this paper, analytical solutions for two point correlators made out of functions with complex conjugated poles or branch points have been obtained in the Minkowski space for the first time. As a special case the Gribov propagator has been considered as well. The result is different from the naive analytical continuation of the correlator primarily defined in the Euclidean space. It is free of ultraviolet divergences and instead of Lehmann it rather satisfies Gribov integral representation.
