N.E. Adam, et al, CLEO Collaboration
TL;DR
This paper reports the first significant measurements of specific light vector-pseudoscalar hadron pairs and three-pion final states from Psi(2S) decays and e+e- annihilation, using CLEO data at CESR.
Contribution
It provides the first significant measurements of certain light hadron final states from Psi(2S) decays and e+e- annihilation, expanding understanding of charmonium decay channels.
Findings
First significant measurements of RhoPi, OmegaPi, RhoEta, and K*0K0bar production.
Observation of Pi+Pi-Pi0 final state from Psi(2S) decays.
Detection of these states in both Psi(2S) decays and direct e+e- annihilation.
Abstract
Using CLEO data collected from CESR e+e- collisions at the Psi(2S) resonance and nearby continuum at E_CM=3.67GeV, we report the first significantly non-zero measurements of light vector-pseudoscalar hadron pair production (including RhoPi, OmegaPi, RhoEta, and K*0K0bar) and the Pi+Pi-Pi0 final state, both from Psi(2S) decays and direct e+e- annihilation.
