Bound-state properties from field-theory correlators
Dmitri Melikhov
We discuss the details of calculating hadron properties from the OPE for correlators of quark currents in QCD, which constitutes the basis of the method of QCD sum rules. The main…
Pion elastic and transition form factors in a broad range of momentum transfers
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
We analyze and , , within the local-duality (LD) version of QCD sum rules, which allows one to obtain predictions for hadron form factors in a bro…
Improved QCD Sum-Rule Approach to Heavy-Meson Decay Constants
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
A visible improvement of the QCD sum-rule framework, achieved only recently by a slightly more sophisticated consideration of the hadron excitations and continuum, is applied to th…
Pion Elastic and pi to gamma gamma* Transition Form Factors at Large Momentum Transfers
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
We present the results of our recent analyses of the form factors F_pi(Q^2) and F_{P gamma}(Q^2), P = pi, eta, eta', within the local-duality version of QCD sum rules. To probe the…
The puzzle of the π-> γγ* transition form factor
Wolfgang Lucha, Dmitri Melikhov
We study the () transition form factors by means of the local-duality (LD) version of QCD sum rules. For the case of and , the conventional LD mode…
Pion Elastic Form Factor in a Rather Broad Range of Momentum Transfers from Local-Duality QCD Sum Rule
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
Revisiting, within QCD sum rules, the relevance of local duality for the pion elastic form factor gives rise to optimism.
Heavy-Quark Masses and Heavy-Meson Decay Constants from Borel Sum Rules in QCD
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Slight sophistications of the QCD sum-rule formalism may have great impact on the reliability of predicted hadron observables, as exemplified for the case of heavy-meson decay cons…
Unprejudiced Look at Effective Continuum Thresholds in Borel Dispersive Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Dispersive sum rules constitute long-standing tools for extracting hadron features from QCD. We estimate the systematic uncertainties induced by assuming quark-hadron duality and i…
Charmed-Meson Decay Constants from Improved QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
The decay constants of the charmed heavy pseudoscalar D and D_s mesons are revisited within a recently developed novel approach to dispersive QCD sum rules which relies on an unpre…
Accuracy of the pion elastic form factor extracted from a local-duality sum rule
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
We analyze the accuracy of the pion elastic form factor predicted by a local-duality (LD) version of dispersive sum rules. To probe the precision of this theoretical approach, we a…
OPE, charm-quark mass, and decay constants of D and D_s mesons from QCD sum rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule extraction of the decay constants of the charmed mesons D and D_s from the two-point correlator of pseudoscalar currents. First, we compare the perturbative e…
Forward-backward and CP-violating asymmetries in rare semileptonic and radiative leptonic B-decays
N. Nikitin, I. Balakireva, D. Melikhov
We study the forward-backward and the CP-violating asymmetries (both time-independent and time-dependent) in rare semileptonic and radiative leptonic B_{d,s}-decays and investigate…
