Data-driven analysis of the system using mathematical models and the role of feedback-loop dynamics

N. G. Stefanis

The data behavior of the pion-photon transition form factor (TFF) is discussed using a nonlinear mathematical model with two parameters and . Analysis shows that the model's…

Improved calculation of the process at low using LCSR's and renormalization-group summation

Sergey Mikhailov, Alexandr Pimikov, N. G. Stefanis

We study two versions of lightcone sum rules to calculate the transition form factor (TFF) within QCD. While the standard version is based on fixed-order pertu…

Cross-link relations between and -meson channels and the QCD vacuum

S. V. Mikhailov, N. G. Stefanis

We discuss cross-link relations between the and -meson channels emerging from two different descriptions of the QCD vacuum: Instanton physics and QCD sum rules with nonlocal…

Extending the application of the LCSR method to low momenta using QCD renormalization-group summation. Theory and phenomenology

S. V. Mikhailov, A. V. Pimikov, N. G. Stefanis

We show that using renormalization-group summation to generate the QCD radiative corrections to the transition form factor, calculated with lightcone sum rules (LCSR), render…

Pion-photon transition form factor in LCSR and tests of asymptotics

N. G. Stefanis

We study the pion-photon transition form factor (TFF) using a state-of-the art implementation of light cone sum rules (LCSRs) within fixed-order QCD perturbation…

Form factor in lightcone sum rules combined with renormalization-group summation vs experimental data

C. Ayala, S. V. Mikhailov, A. V. Pimikov +1

We consider the lightcone sum-rule (LCSR) description of the pion-photon transition form factor in combination with the renormalization group of QCD. The emerging scheme represents…
