Masses and OZI-Allowed Decay Widths of γ States in a Coupled Channel Model

概要

• 論文の詳細を見る

• A coupled channel model based on an effective quark interaction Hamiltonian and an OBE potential for meson-antimeson interactions is applied to the analysis of both masses and strong decay widths of γ states. It turns out to be quite successful, following the previous successful result for the ψ states. It is concluded that the effective quark interaction Hamiltonian fully explains dynamics not only for mass splitting but also for the Okubo-Zweig-Iizuka (OZI) allowed decay of heavy quarkonia. The most conspicuous prediction of the present model is the mass, 〜10.670 GeV, and the width, 〜20 MeV, of a yet unobserved γ(3D) resonance, which may correspond to the observed structure of the e^+e^- cross-section R seen in the energy range 10.6-10.8 GeV.
