英文摘要The enigmatic charged states Z(c)(3900), Z(c)(4020), Z(c)(4050), Z(b)(10610), and Z(b)(10650) are studied within a coupled-channel Schrodinger model, where radially excited quark-antiquark pairs, with the same angular momenta and isospin as the a(1)(1260) and b(1)(1235), are strongly coupled to their Okubo-Zweig-Iizuka-allowed decay channels D (D) over bar* + (D) over barD* and D*(D) over bar*, or B (B) over bar* + (B) over barB* and B*(B) over bar*, in S and D waves. Poles, matching the experimental mass and width of the above states, are found by varying only two free parameters. From the wave-function analysis of each resonance, the probability of each of the components contributing to the coupled system is estimated, and predictions can be made for the relative decay fractions among the coupled open-charm or open-bottom decay channels.
