The SVZ method: Why it works and why it fails
Abstract
We show in the context of potential theory, first, why the SVZ procedure for calculating hadronic masses succeeds phenomenologically: it provides a semiclassical interpolating formula which correctly relates input masses to output masses; and second, why it fails theoretically: the potential (or QCD) parameters derived from fits to masses are necessarily different from the true parameters.
