Distinguishing near-threshold pole effects from cusp effects
发表期刊PHYSICAL REVIEW D
语种英语
摘要We make use of a unitarized coupled-channel model to analyze the mass distribution data of final states in production processes of X(4260). By analyzing the analytical structures of the decay amplitudes, we find that the line shape of the Z(c)(3900) signal is related to the combined effect of a pair of near-threshold "shadow" poles and the (D (D) over bar*)(+/-) thresholds, in which the third-sheet pole might provide a dominant contribution. As all the coupled channels effects are tuning off, the trajectories of these two poles suggest that the Z(c)(3900) might originate from the attractive interaction of (D*(D) over bar*)(+/-) through a long-distance interaction, e.g., pi-exchange interaction, as a "deuteron-like" state. There is no nearby pole structure corresponding to the Z(c)(4025) signal in the (D*(D) over bar*)(+/-) mass distribution.
