Description
Solution of Schwinger-Dyson and Bethe-Salpeter Equations for excited and
ground state pions will be presented. The quark gap equation has been solved directly
in our Minkowski space-time and the solution, according to confinement, does not allow a free quark propagation. The Minkowski space solution for confining QCD
as will be shown, is not only numerically accessible, but also
provides a reasonable description of the pseudoscalar meson system. An unknown and unusual features of confinement in Minkowski space will be discussed for unobservable QCD Greens function as well us the implication for observables will be mentioned. The question in the title will not be answered by the speaker.
