η(1405/1475)和X(1835)的性质是轻强子物理领域研究的热点之一。研究它们的味道结构能为确定其性质提供非常有力的实验证据。味道过滤器过程可以用来研究上述共振态的味道结构。X->γV和J/ψ->φX过程可以作为味道过滤器，其中X是某共振态。BESIII探测器现在已经累计获得了世界上最大统计量的J/ψ事例数据样本，这为进一步研究共振态的味道结构提供了前所未有的机会。. 本项目中具体的研究内容如下：(1)通过J/ψ->γγω的衰变过程寻找η(1405/1475)->γω和X(1835)->γω的衰变模式；(2)寻找J/ψ->φX(1835), X(1835)->η’ππ的衰变模式。这两个工作将为研究η(1405/1475)和X(1835)的味道结构提供非常重要的实验证据，进而可以验证某些理论模型。

The nature of η(1405/1475) and X(1835) has been one of the hot topics in light hadron physics. Powerful experimental evidence can be obtained by studying the flavor structures of η(1405/1475) and X(1835). The flavor structures of the resonances can be studied with flavor filter. The processes of X->γV and J/ψ->φX can be acted as the flavor filters, where X for the resonances. The BESIII detector has accumulated the largest data sample of J/ψ in the world, which provides unprecedented opportunities for studying the flavor structures. . The research subjects include: (1) search for the η(1405/1475)->γω and X(1835)->γω in J/ψ->γγω process; (2) search for J/ψ->φX(1835), X(1835)->η’ππ. Both of the two work can provide useful information in studying flavor structures of η(1405/1475) and X(1835), which can provide the verification for some of the theory models.
