Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.

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.
