Pion form factor analysis using NLO analytic perturbation theory
N. G. Stefanis
I present results for the pion's electromagnetic form factor in the spacelike region, which implement the most advanced perturbative information currently available for this observ…
Deep inside the pion. Reconciling QCD theory with data
A. P. Bakulev, S. V. Mikhailov, N. G. Stefanis
Recent developments in the QCD description of the pion structure are reviewed. The CLEO pion-photon transition data analysis favors a distribution amplitude for the pion that is do…
The gluon content of the and mesons
N. G. Stefanis, S. S. Agaev
We analyze power-suppressed contributions to singlet pseudoscalar and meson transition form factors. These corrections stem from endpoint singularities and help im…
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…
Pion form factor in QCD: From nonlocal condensates to NLO analytic perturbation theory
A. P. Bakulev, K. Passek-Kumerički, W. Schroers +1
We present an investigation of the pion's electromagnetic form factor F_π(Q^2) in the spacelike region utilizing two new ingredients: (i) a double-humped, endpoint-suppressed pion…
