Form factor π0γ*γ in lightcone sum rules combined with renormalization-group summation vs experimental data.

Form factor π0γ*γ in lightcone sum rules combined with renormalization-group summation vs experimental data.

We consider the lightcone sum-rule (LCSR) description of the pionphoton transition form factor in combination with the renormalization group of QCD. The emerging scheme represents a certain version of Fractional Analytic Perturbation Theory and significantly extends the applicability domain of pertu...
