Title: Transition form factor of γ → 3π in a nonlocal quark model
Creator: Zhevlakov, Alexey S.

Description: The transition form factor of a gamma into three pions F3π are studied in a framework of nonlocal chiral quark model. In local limit the result is agreement with chiral perturbative theory and reproduce Wess-Zumino-Witten anomaly. Availability of nonlocality not change a value of transition form factor in chiral limit. On the physical threshold of reaction, the transition form factor F3π is obtained close to the experimental data on account of current mass of quark.
