Query: Effective Continuum Thresholds for Quark-Hadron Duality in Dispersive
  Sum Rules   Modifying the standard approaches to nonperturbative QCD based on
Borel-transformed dispersive sum rules by allowing the effective continuum
thresholds required for the implementation of quark-hadron duality to depend on
the Borel parameters and on any relevant momentum promises to provide higher
accuracy and reliable error estimates for the extracted predictions of hadron
characteristics. A careful analysis reveals that the exact effective continuum
thresholds do indeed exhibit dependence on the Borel parameter (and on external
momenta) and that they are not universal but vary with the correlators under
consideration. The striking similarity of our hadron-parameter extraction
procedures in QCD, on the one hand, and quantum-theoretical potential models,
on the other hand, calls for application of the proposed techniques in QCD.
