Hadronic Decays of Excited Heavy Quarkonia
Abstract
We construct an effective Lagrangian for the hadronic decays of a heavy excited s-wave-spin-one quarkonium into its ground state. We show that reasonable fits to the measured invariant mass spectra in the J/ and systems can be obtained working in the chiral limit. The mass dependence of the various terms in the Lagrangian is discussed on the basis of a quark model.
