Is a momentum space of quantum fields Euclidean?

The Wick rotation provides the standard technique of computing Feynman diagrams by means of Euclidean propagators. It is the Laplace transform from a Minkowski coordinate space to the Euclidean momentum one.

Then one can suppose that a momentum space of quantum fields in an interaction zone really is Euclidean.
