Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties…
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expan…
Quark-Hadron Duality and Effective Continuum Thresholds in Dispersive Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
A novel procedure for extracting hadron characteristics from QCD sum rules, based on effective continuum thresholds (necessary for the implementation of quark-hadron duality) which…
Local-duality QCD sum rule for the pion elastic form factor
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
This work presents the results of our analysis of the accuracy of the pion form factor derived from the local-duality version of QCD sum rules.
Analytic Quest for Confining Interaction Kernels in Instantaneous Bethe-Salpeter Equations
Wolfgang Lucha
The Salpeter equation, a standard tool in hadron physics, constitutes a well-defined three-dimensional approximation to the Bethe-Salpeter formalism for the description of bound st…
