Analysis of 1/Nc Corrections in the Quark Model for the Pion Transition Form Factor

Analysis of 1/Nc Corrections in the Quark Model for the Pion Transition Form Factor

\(1{\text{/}}{{N}_{c}}\) corrections in the framework of nonlocal quark model are analyzed. The initial stage of generating diagrams is carried out in the QGRAF program. The data generated by QGRAF is processed and diagrams are selected with \(1{\text{/}}{{N}_{c}}\) counting rules. The diagrams are classified to certain types. Subsequently, the expressions are transferred to the FORM analytical calculation program. The analysis of the Feynman diagrams for the pion transition form factor is performed.
