Effective Continuum Thresholds for Quark-Hadron Duality in Dispersive Sum Rules

Year: 2010
Type: conference-paper
Abstract: 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 entail higher accuracy and reliable error estimates for the extracted predictions of hadron features.
