最近在B工厂观察到的状态的统一描述
A Uniform Description of the States Recently Observed at B-factories
摘要：
新发现的Y（4260），Y（4361），Y（4664）和Z $^\pm$（4430）激发了人们对粲偶素光谱学研究的兴趣。先前观察到的Y（4260）被解释为杂化态、分子态和重子态等。本文首次证明了这些很难解释为粲偶素态的新结构可以系统地嵌入到扩展的重子态图象中。根据这一任务，迄今已知的这些状态的特征是可以理解的。并且，在同一个框架中，我们为实验者在未来进行测量做出了一些预测。
英文摘要：
The newly found states Y(4260), Y(4361), Y(4664) and Z$^\pm$(4430) stir broad interest in the study of spectroscopy in a typical charmonium scale. The Y(4260) which was observed earlier has been interpreted as hybrid, molecular state, and baryonium, etc. In this note we show for the first time that these new structures, which are hard to be interpreted as charmonium states, can be systematically embedded into an extended baryonium picture. According to this assignment, the so far known characters of these states are understandable. And, in the same framework, we make some predictions for experimenters to measure in the future.
