The nature of the Y(4260) remains unclear despite or because of high precision data being available now. The resonance structure seems to be multifaceted and at least part of the structure is discussed in terms of exotic hadrons. Thus the goal of the project is to measure the decay channels of the Y(4260) region to clarify the structure and the properties of the underlying states with the potential to discover also so far unknown mesonic or baryonic states in the decays.In order to check for as many channels as possible in an unbiased way, the studies will be performed by analyzing (semi-)inclusive recoil-spectra of a couple of hadrons.

尽管或因为现在有高精度的数据，Y(4260)的性质仍然不清楚。共振结构似乎是多方面的，至少部分结构是从奇异强子的角度进行讨论的。因此，该项目的目标是测量Y(4260)区的衰变通道，以澄清基本态的结构和性质，并有可能在衰变过程中发现迄今未知的介子或重子态。为了以公正的方式检查尽可能多的通道，将通过分析几个强子的(半)包含反冲谱来进行研究。
