Description

We make use of the renormalization group summation in conjunction with the well-known light cone sum rules (LCSR) to obtain the QCD radiative corrections to the electromagnetic and transition pion form factor (emFF and TFF, respectively) for spacelike in the mid-energy range of transfer momenta Q2. The prediction calculated herewith reproduces the experimental data below/around 1 GeV^2 significantly better than analogous predictions based on a fixed-order power-series expansion in the strong coupling constant.
