New Measurement of Exclusive Decays of the chic0 and chic2 to Two-Meson Final States
Abstract
Using a sample of 2.59 times 107 psi(2S) decays collected by the CLEO--c detector, we present results of a study of chic0 and chic2 decays into two-meson final states. We present the world's most precise measurements of the chicJ,(J=0,2) -> pi+pi-, pi0 pi0, K+K-, K0S K0S, eta eta and etaprime etaprime branching fractions, and a search for chic decays into eta etaprime. These results shed light on the mechanism of charmonium decays into pseudoscalar mesons.
