Study Of The Process E(+)E(-) -> Pi(0)Pi(0)Gamma In C.M. Energy Range 600-970 Mev At Cmd-2

The cross section of the process e(+)e(-) --> pi(0)pi(0)gamma has been measured in the c.m. energy range 600-970 MeV with the CMD-2 detector. The following branching ratios have been determined: B(rho(0) --> pi(0)pi(0)gamma) = (5.2(-1.3)(+1.5) +/- 0.6) x 10(-5) and B(omega --> pi(0)pi(0)gamma) = (6.4(-2.0)(+2.4) +/- 0.8) x 10(-5). Evidence for the rho(0) --> f(0)(600)gamma decay has been obtained: B(rho(0) --> f(0)(600)gamma) = (6.0(-2.7)(+3.3) +/- 0.9) x 10(-5). From a search for the process e(+)e(-) --> etapi(0)gamma the following upper limit has been obtained: B(omega --> etapi(0)gamma) < 3.3 x 10(-5) at 90% CL. (C) 2003 Published by Elsevier B.V.
