Abstract: (Elsevier)

About 11 200 e + e − → ω → π + π − π 0 events selected in the center of mass energy range from 760 to 810 MeV were used for the measurement of the ω meson parameters. The following results have been obtained: σ 0 =(1457±23±19) nb, m ω =(782.71±0.07±0.04) MeV/c 2 , Γ ω =(8.68±0.23±0.10) MeV, Γ e + e − ·Br( ω → π + π − π 0 )=(0.528±0.012±0.007)·10 −3 MeV.
