迄今为止，人们对很多类粲偶素态的特性仍未给出非常明确的答案。Y(4260)作为非常重要的一个类粲偶素态，多个实验对其共振参数和衰变特性开展了大量的研究，发现了一些显性和隐性含粲衰变过程。然而仍未发现任何到轻强子末态的衰变。本项目利用4-4.6GeV能区采集的实验数据，通过测量多重子末态截面谱，确定Y(4260)共振参数及确立其不含粲末态衰变。本项目的实验结果能帮助我们深入理解Y(4260)的本质和衰变特性。本项目还利用这些末态中两个重子的不变质量谱，寻找双重子态和六夸克态，为未来的超级tau粲工厂预研提供参考。

Until now, it is too unclear to get the picture of the properties of charmonium-like states. As a very important charmonium-state, the resonance parameters and decay properties of Y(4260) have been studied by several experiments, and some open charm as well as hidden charm processes have been discovered. Light-hadron final states, however, are not observed..Based on the data sets taken between 4 and 4.6 GeV, we propose to measure the cross-section spectra of the multi-baryon states, and determine the Y(4260) resonance parameters and non-charm decays. The measured results can help us understand the nature of Y(4260). Furthermore, we study the invariant mass spectra of two baryons or anti-baryons for dibaryon or hexaqurk searches, which will provide physics topics for the pre-design of super tau charm factory project.
