Evidence for hc Production from psi-prime at CLEO

TL;DR

This paper reports a search for the h_c charmonium state produced in psi-prime decays using CLEO detector data, aiming to identify a specific quantum state of charm quark-antiquark pairs.

Contribution

First search for h_c production in psi-prime decays using CLEO data, providing preliminary results on this charmonium state.

Findings

Estimated ~ 3 million psi-prime events analyzed

Search for h_c via psi-prime -> pi^0 h_c decay channel

Preliminary results reported

Abstract

Using the ~ 6 pb-1 of e+e- annihilation data taken at psi-prime(3686) with CLEO III and CLEO-c detectors with estimated ~ 3.0 million psi-prime events, we have searched for the h_c(1^1P_1) state of charmonium in the reaction psi-prime(3686) -> pi^{0} hc -> (gamma gamma) (gamma eta_c). The preliminary results are reported.
