论文摘要
BESIII实验已通过$ e^{+} e^{+} e^{ - } $ collision收集了约20 fb $^{ - 1} $光度数据。在本次演讲中，我们介绍了最近在besiii的$ xyz $结果，包括$ y（4220）$的质量和宽度测量，搜索具有罕见衰减模式的$ y $状态，isospin parity的确定为$ z_ {c}^{0}（3900）（3900）$，以及质量和宽度的确定，以及$ x的确定，以及$ x的$ x（382）$ x.387 $x.387。
BESIII experiment has collected about 20 fb$^{-1}$ luminosity data between $\sqrt{s}=3.8$ and 4.7 GeV via $e^{+}e^{-}$ collision. In this talk, we present the recent $XYZ$ results at BESIII, including mass and width measurements of $Y(4220)$, search for $Y$ states with rare decay modes, isospin parity determination of $Z_{c}^{0}(3900)$ as well as the mass and width determination, and search for new decay modes of $X(3872)$.
