标题： Charmonium: Conventional and $XYZ$ States in a Relativistic Screened Potential Model

摘要： 在本工作中，对规范介子态的质量谱和衰变性质进行了全面的相对论框架分析。 规范介子态的当前实验状态得到了回顾。 利用一种屏蔽势模型，我们计算了 $c\bar{c}$束缚系统的谱和各种衰变宽度，并将我们的结果与实验数据和现有的理论模型进行比较。 我们计算了衰变常数， $E1$ 和 $M1$ 转换以及湮灭衰变宽度，确认了我们的模型与实验观测结果在已确立的规范介子态上的一致性。 作为$P$波态的charm介子态$X(4140)$、$X(4274)$和$X(4500)$以及作为$S-D$混合态的$\psi(4040)$、$\psi(3770)$、$\psi(4160)$、$\psi(4230)$、$\psi(4360)$、$\psi(4415)$、$Y(4500)$和$Y(4360)$的解释被进行。 显示英文摘要

摘要： In this work a comprehensive analysis of the mass spectrum and decay properties of charmonium states within a relativistic framework is carried out. The present experimental status of charmonium states is reviewed. Utilizing a screened potential model, we compute the spectra and various decay widths for $c\bar{c}$ bound system, comparing our results with experimental data and existing theoretical models. We calculate the decay constants, $E1$ and $M1$ transitions, and annihilation decay widths, confirming the consistency of our model with experimental observations for well-established charmonium states. The interpretation of charmonium-like states, $X(4140)$, $X(4274)$, and $X(4500)$ as $P$ wave charmonium states and $\psi(4040)$, $\psi(3770)$, $\psi(4160)$, $\psi(4230)$, $\psi(4360)$, $\psi(4415)$, $Y(4500)$ and $Y(4360)$ as $S-D$ mixed charmonium states are carried out.
