Findings

Measured branching fractions for several decay modes.

Performed Dalitz plot analysis for selected decay channels.

Provided preliminary results on decay substructures.

Abstract

Using a sample of 3x10^6 psi(2S) decays recorded by the CLEO detector, we study three body decays of the chi_{c0}, chi_{c1}, and chi_{c2} produced in radiative decays of the psi(2S). We consider the decay modes pi+ pi- eta, K+ K- eta, p pbar eta, pi+ pi- etaprime, K+ K- pi0, p pbar pi0, pi+ K- K0S, and K+ pbar Lambda measuring branching fractions or placing upper limits. For chi_{c1} to pi+ pi- eta, K+ K- pi0, and pi+ K- K0S our observed samples are large enough to study the substructure in a Dalitz plot analysis. The results presented in this document are preliminary.
