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…
