Analyticity properties of three-point functions in QCD beyond leading order
A. P. Bakulev, A. I. Karanikas, N. G. Stefanis
The removal of unphysical singularities in the perturbatively calculable part of the pion form factor--a classic example of a three-point function in QCD--is discussed. Different `…
Pion distribution amplitude -- from theory to data (CELLO, CLEO, E-791, JLab F(pi))
Alexander P. Bakulev
In my talk I discuss the theoretical and experimental status of the pion distribution amplitude (DA). I show that the QCD sum rule method with nonlocal condensates (NLC) for the pi…
Pion structure: from nonlocal condensates to NLO analytic perturbation theory
N. G. Stefanis, A. P. Bakulev, S. V. Mikhailov +2
A pion distribution amplitude, derived from nonlocal QCD sum rules, has been employed to calculate using light-cone sum rules, and in NLO QCD perturb…
Mapping out the quark structure of hadrons in QCD
Alexander P. Bakulev, S. V. Mikhailov, N. G. Stefanis
In the context of QCD sum rules with non-local condensates we present a pion distribution amplitude, which is double-humped with its end-points x\to(0,1) strongly suppressed, and s…
What is this thing called pion distribution amplitude? From theory to data
Alexander P. Bakulev, S. V. Mikhailov, N. G. Stefanis
We discuss the status of the pion distribution amplitude (DA) from analyzing the CLEO experimental data in the context of QCD sum-rule techniques and QCD perturbation theory at the…
New shapes of the rho-meson light-cone distribution amplitudes: how can they influence the B --> rho e nu decay form factors
A. P. Bakulev, S. V. Mikhailov, R. Ruskov
We present new models of the rho-meson leading-twist light-cone distribution amplitudes based on the QCD sum rule approach with nonlocal condensates. Their shapes differ noticeably…
