Observation of etac' Production in gamma-gamma Fusion at CLEO
Abstract
We report on the observation of the etac' (2 1S0), the radial excitation of etac (1 1S0) ground state of charmonium, in the two-photon fusion reaction gamma gamma to etac' to KS0 K pi in 13.4 fb-1 of CLEO II/II.V data and 9.2 fb-1 of CLEO III data. The data have been analyzed to extract the etac' resonance parameters.
