摘要：

Results from a numerical study of the QCD Schwinger-Dyson (SD) equation indicate that the Wick rotation may be disallowed due to the presence of complex branch points in the quark propagator. Atkinson and Blatt obtained a similar result in a study of massless QED. This leads us to suggest that the preferred defining metric for such confining theories is Euclidean, as has also been suggested for quantum gravity. © 1990.
