Improved estimates of the pion-photon transition form factor in the (1 ≤ Q2 ≤ 5) GeV2 range and their theoretical uncertainties
We consider the pion-photon transition form factor at low to intermediate spacelike momenta within the theoretical framework of light-cone sum rules. We derive predictions which take into account all currently known contributions stemming from QCD perturbation theory up to the next-to-next-to-leadin...
