f1(1285) → e+e- decay and direct f1 production in e+e- collisions

The width of the f(1)(1285) -> e(+)e(-) decay is calculated in the vector meson dominance model. The result depends on the relative phase between two coupling constants describing f(1) > rho(0)gamma decay. The width Gamma(f(1) -> e(+)e(-)) is estimated to be similar or equal to 0.07 - 0.19 eV. Direct f(1) production in e(+)e(-) collisions is discussed, and the e(+)e(-) -> f(1) > a(0)pi -> eta pi pi cross section is calculated. Charge asymmetry in the e(+)e(-) -> eta pi(+)pi(-) reaction due to interference between e(+)e(-) -> f(1) and e(+)e(-) -> eta rho(0) amplitudes is studied.
