Abstract

Using 5.63 pb(-1) of data accumulated at the psi(2S) resonance with the CLEO III and CLEO-c detectors corresponding to 3.08x10(6) psi(2S) decays, a search is performed for the decay psi(2S)->eta(c)pi(+)pi(-)pi(0) to test a theoretical prediction based upon the assumption that the cc pair in the psi(2S) does not annihilate directly into three gluons but rather survives before annihilating. No signal is observed, and a combined upper limit from six eta(c) decay modes is determined to be B(psi(2S)->eta(c)pi(+)pi(-)pi(0))<= 1.0x10(-3) at 90% C.L. This upper limit is about an order of magnitude below the theoretical expectation.
