Abstract

The new particle Z(3930) found by the Belle and BaBar Collaborations through the γ γ to DD process is identified to be the χ _c2(2P) state. Since the mass of this particle is above the D threshold, the OZI-allowed two-body strong decays are the main decay modes. In this paper, these strong decay modes are studied with two methods. One is the instantaneous Bethe-Salpeter method within Mandelstam formalism. The other is the combination of the ³ P ₀ model and the former formalism. The total decay widths are 26.3 MeV and 27.3 MeV for the methods with or without the ³ P ₀ vertex, respectively. The ratio of which changes along with the mass of the initial meson is also presented.
