Sažetak (engleski)
Motivated by the ongoing measurements of the Primakoff process π−γ∗→π−π0 by the COMPASS Collaboration at CERN, the transition form factor for the canonical anomalous process γ∗→π+π0π− is calculated in a constituent quark-loop model. The simplest contribution to this process is the quark “box” amplitude. In the present paper we also explicitly include the vector meson degrees of freedom, i.e., the ρ and the ω, thus giving rise to additional, resonant contributions. We find that in order to satisfy the axial anomaly result, a further subtraction in the resonant part is needed. The results are then compared with the vector meson dominance model as well as the Dyson-Schwinger calculations, the chiral perturbation theory result, and the available data.
