Observation of ηc → ρ0ρ0 and review of other ηc decay modes
Description
Branching ratio measurements for ηc decays into ΦΦ, K+K-π0, K0SK+-π-+, pantip are presented. For the previously unobserved ρ0ρ0 mode a preliminary measurement is reported. The dominant contribution of the ρ0ρ0 intermediate state to the ηc decay into 4π+- is evidenced by a multichannel analysis and strongly supported by the study of pseudoscalar contribution and ρ mass cuts. 8 refs
