The width of the f1(1285) → e+e+e- decay is calculated in the vector meson dominance model. The result depends on the relative phase between two coupling constants describing f1 → ρ0γ decay. The width Γ( f1 → e+e+e-) is estimated to be ≃ 0:07 - 0:19 eV. Direct f1 production in e+e+e- collisions is discussed, and the e+e+e- → f1 → a0π → ηππ cross section is calculated. Charge asymmetry in the e+e+e- → ηπ+π- reaction due to interference between e+e+e- → f1 and e+e+e- → ηρ0 amplitudes is studied.

Suitable Notion

Electromagnetic interactions are introduced in the effective chiral Lagrangian for heavy mesons which includes light vector particles. A suitable notion of vector meson dominance is formulated. The constraints on the heavy meson-light vector and heavy meson-light pseudoscalar coupling constants are obtained using experimental D*→Dγ branching ratios. These constraints are compared with values estimated from semileptonic transition amplitudes as well as from extension of the light meson coupling pattern. Application to the heavy baryon spectrum in the “bound state” model is made.
