Dorofeev, A. Ekimov, Yu. Gouz, A. Ivashin, I. Kachaev, A. Karyukhin, Yu. Khokhlov, V. Konstantinov, V. Matveev, V. Nikolaenko, B. Polyakov, D. Ryabchikov, N. Shalanda, M. Soldatov, A. Solodkov, A. Solodkov, O. Solovianov, A. Zaitsev] The isospin symmetry-breaking (ISB) decay f 1(1285) → π+π−π0 has been studied at the VES facility. The branching ratio is measured: $\frac{{BR\left( {f_1 \to \pi ^ + \pi ^ - \pi ^0 } \right)}} {{BR\left( {f_1 \to \eta \pi ^ + \pi ^ - } \right)}} = 0.86 \pm 0.16_{ - 0.20}^{ + 0.70} \%$ . An upper limit for the f 1 decay into ρ(770)π is obtained: BR(f 1(1285) → ρ +−π−+) < 0.31% at 95% CL. The Author(s), 2011 Dorofeev V. Institute for High Energy Physics, Protvino, Russia aut Ekimov A.
