Experimental study of the decay PHI(1020)--->ETA+GAMMA in multi-photon final state
In the SND experiment at VEPP-2M e^+e^- collider the phi(1020) ---> eta+gamma
---> 3pi^0+gamma decay was studied. The branching ratio B(phi--->eta+gamma) =
(1.246 +- 0.025 +- 0.057)% was measured.Comment: 4 pages, 1 figure, 1 table, Submitted to JETP Let
Experimental study of the e^+e^-\to\pi^+\pi^-\pi^0 reaction by SND detector in the energy range sqrt{s}=0.42--1.38 GeV
The review of the SND results of the process study
in the energy range -- 1.38 GeV at VEPP-2M collider, based on
about selected events, is presented. The total cross section,
parameters of the , , resonances, and ,
states were obtained. It was found that and
intermediate states describe the reaction dynamics. The
experimental data cannot be described by a sum of only , ,
and resonances contributions. This can
be interpreted as a manifestation of the decay, suppressed by
-parity, with relative probability .Comment: 6 pages and 2 figures. Talk given at the X International Conference
