N2 - The width of the f1(1285)→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-) is estimated to be ≃0.07-0.19 eV. Direct f1 production in e+e- collisions is discussed, and the e+e-→f1→a0π→ηππ cross section is calculated. Charge asymmetry in the e+e-→ηπ+π- reaction due to interference between e+e-→f1 and e+e-→ηρ0 amplitudes is studied.
