A puzzle of the pion-photon transition form factor - resolved?
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
By means of QCD sum rules in local-duality limit, we analyze the behaviour of the form factors for the transitions of a real and a virtual photon to some pseudoscalar meson as func…

Pseudoscalar-Meson Form Factors: A Fresh Look by QCD Sum Rules
Irina Balakireva, Wolfgang Lucha, Dmitri Melikhov
Confronted with some surprising claims about experimentally measured or theoretically expected dependencies on the involved momentum transfer of various form factors of pseudoscala…

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.
