论文摘要
研究共振性质的几种方法应用于最近在Bottonomium和Charmon扇区中发现的共振。我们采用了有效范围的扩展，宽度的饱和度和共振的成分以及直接拟合数据。后者源于通用$ s $ -matrix参数化，该参数解释了与通道相关的相关动力学特征，这些动力学特征在共振质量周围的能量区域中强烈彼此，其阈值也在其中。我们报告使用这些方法获得的结果$ z_b（10610）$，$ z_b（10650）$，$ z_ {cs}（3985）$，$ z_c（3900）$，$ x（4020）$，$ x（4020）$，$ x（6900）$，$ x（6825）$ x（6825）$，$ p_} $，和$ p_}（cs}（444.44444,44,44444,44,44,44,44,44,44,44,44,44,44,44,44,44,44,44,4,44,4,44,44,44,44,44,44,44,44,44,44,4,44,4,44,4,44,4,44。
Several methods for studying the nature of a resonance are applied to resonances recently discovered in the bottonomium and charmonium sectors. We employ the effective-range expansion, the saturation of the width and compositeness of a resonance, as well as direct fits to data. The latter stem from generic $S$-matrix parameterization that account for relevant dynamical features associated to channels that couple strongly in an energy region around the resonance masses, in which their thresholds also lie. We report on results obtained with these methods for the resonances $Z_b(10610)$, $Z_b(10650)$, $Z_{cs}(3985)$, $Z_c(3900)$, $X(4020)$, $X(6900)$, $X(6825)$, and $P_{cs}(4459)$.
