chic0 and chic2 Decays into eta eta, eta eta', and eta' eta' Final States

Original · EN

Using a sample of 3 x 10⁶ psi(2S) decays collected by the CLEO III and CLEOc detector configurations, we present results of a study of χc₀ and χc₂ decays into eta-eta, eta-etaprime, and etaprime-etaprime final states. We find B(chic₀ -> eta-eta)= (0.31+-0.05+-0.04+-0.02)%, B(chic₀ -> eta-etaprime) <0.05 % at the 90% confidence level, and B(chic₀ -> etaprime-etaprime) = (0.17 +- 0.04 +-0.02 +-0.01)%. We also present upper limits for the decays of χc₂ into these final states. These results give information on the decay mechanism of χc states into pseudoscalars.
