Measurements of $\psip$ decays into $\gamma K\bar{K}\pi$ and $γη\pipi$

Abstract

Radiative decays of the $\psip$ into $\gamma K\bar{K}\pi$ and $γη\pipi$ final states are studied using 14 million $\psip$ events collected with the BESII detector. Branching fractions or upper limits on the branching fractions of $\psip$ and $\xcj$ decays are reported. No significant signal for $\etafl/\etafh$ is observed in the $K\bar{K}\pi$ or $η\pipi$ mass spectra, and upper limits on the branching fractions of $\psip\rarγ\etaf$, $\etaf\rar K\bar{K}π$ and $η\pipi$ are determined.
