| 英文摘要 | We demonstrate that the recently observed X, Y, Z states cannot be purely from kinematic effect. Especially the narrow near-threshold structures in elastic channels call for nearby poles of the S - matrix which can be used to distinguish them from the normal kinematic cusp effect. In addition, it is also discussed how spectra can be used to distinguish different scenarios proposed for the structure of those poles, such as hadro-quarkonia, tetraquarks and hadronic molecules. The basic tool employed is heavy quark spin symmetry. |
