Pion form factor from local-duality QCD sum rule

Wolfgang Lucha, Dmitri Melikhov

We present our recent results for the pion elastic form factor [1] obtained within a local-duality three-point sum rule (a Borel sum rule in the limit of an infinite Borel paramete…

How reliable are bound-state parameters obtained from QCD sum rules?

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We discuss the extraction of ground-state parameters, such as decay constants and form factors, from two- and three-point dispersive sum rules, making use of a quantum-mechanical p…

Extracting Hadron Parameters from Dispersive Sum Rules

Wolfgang Lucha, D. Melikhov, S. Simula

Puzzled or surprised by the almost incredible accuracy occasionally claimed in the literature to be achievable for numerical outcomes of QCD sum-rule analyses, we scrutinized the u…

Hadron form factors from sum rules for vacuum-to-hadron correlators

Dmitri Melikhov

We analyse the extraction of the bound-state form factor from vacuum-to-hadron correlator, which is the basic object for the calculation of hadron form factors in the method of lig…

Accuracy of bound-state form factors extracted from dispersive sum rules

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We discuss the extraction of form factors from three-point sum rules making use of harmonic-oscillator model, where we derive the exact expression for the relevant correlator. We d…

Light-cone expansion of heavy-to-light form factors

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We present the results of our recent systematic study of the light-cone expansion of heavy-to-light transition form factors in a model with scalar constituents [1]. We show that th…
