In this study, the properties of the $J^{PC}=1^{++}$ hidden charm poles are analyzed under the variation of the bare 2P charmonium mass within the effective field theory proposed in Ref. [1]. The main focus of the current work is on the pole trajectory of the ${\chi }_{c1}(2P)$ charmonium dressed by the $D{\overline{D}}^{⁎}$ meson loops. It is shown that the trajectories of the pole change radically for values of the bare charmonium mass above a certain value and also depending on how close the pole is to the threshold.

Charmonium 对有效场论中1 ⁺⁺隐藏魅力极特性的影响

在本研究中， $J^{磷C}=1^{++}$在参考文献中提出的有效场理论中，在裸露的 2P 魅力质量变化下分析了隐藏魅力极点。[1]。当前工作的主要重点是极点轨迹${\chi }_{C1}(2磷)$ Charmonium 穿着 $D{\overline{D}}^{⁎}$介子环。结果表明，当裸露的魅力质量值高于某个值时，极点的轨迹会发生根本变化，并且还取决于极点与阈值的接近程度。
