Abstract
About 11 200 e(+)e(-) -> pi(+) pi(-) pi(0) events selected in the center of mass energy range from 760 to 810 MeV were used for the measurement of the omega meson parameters. The following results have been obtained: sigma(0) = (1457 +/- 23 +/- 19) nb, m(omega) = (782.71 +/- 0.07 +/- 0.04) MeV/c(2), Gamma(omega) = (8.68 +/- 0.23 +/- 0.10) MeV, Gamma(e+e-). Br(omega -> pi() pi(-) pi(0))=(0.528 +/- 0.012 +/- 0.007) . 10(-3) MeV. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
