Description

Radiative decays of the ψ(2S) into γKKπ and γηπ+π- final states are studied using 14x106 ψ(2S) events collected with the BESII detector. Branching fractions or upper limits on the branching fractions of ψ(2S) and χcJ decays are reported. No significant signal for η(1405)/η(1475) is observed in the KKπ or ηπ+π- mass spectra, and upper limits on the branching fractions of ψ(2S)→γη(1405)/η(1475), η(1405)/η(1475)→KKπ, and ηπ+π- are determined
