Description

The decay f1(1285) → ρ0(770)γ was studied at VES spectrometer of IHEP. Clear signal of f1(1285) is seen in the effective mass spectrum of the π+π-γ system in the reaction π-N → π+π-π-γN at the momentum Pπ- = 37 GeV/c. The branching fraction of decay f1(1285) → ρ0(770)γ has been found to be BR(f1(1285) → ρ0(770)γ) = (2.8 ± 0.7(stat) ± 0.6(syst)).10-2. The ratio of the helicity amplitudes for ρ0 meson in its rest frame was determined by the analysis of angular distributions: (orig.)
