摘      要：The enigmatic charged states Zc(3900), Zc(4020), Zc(4050), Zb(10610), and Zb(10650) are studied within a coupled-channel Schr¨odinger model[1], where radially excited quark-antiquark (qˉq) pairs, with the same angular momenta and isospin as the a1(1260) and b1(1235), are strongly coupled to their Okubo-Zweig-Iizuka - allowed de-cay channels DˉD+ ˉDD and DˉD, or BˉB+ ˉBB and BˉB, in S and D-wave. Poles, matching the experimental mass and width of all the above states, are found by varying only two free parameters.
