论文摘要
在Diquark Diantiquark构图中,我们研究了隐藏的魅力Tetraquark Systems($ cq \ bar {c} \ bar {q} $,$ cs \ bar {c} \ bar {c} \ bar {s} $和$ cs \ bar {c} \ bar {c} \ bar {q} $)使用linear ponflints。在这项研究中,我们将四个身体系统分为三个随后的两个身体系统。为了消除介体和四夸克状态的S和P波质量中的变性,采用了旋转旋转,自旋轨道,旋转轨道和张量的组件。在这种尝试中,我们能够将$ψ(4230)$分配为纯$ cq \ bar {c} \ bar {q} $ tetraquark state。 $ψ(4360)$和$ψ(4390)$作为纯$ cs \ bar {c} \ bar {q} $ tetraquark states。根据我们的分析,$ψ(4260)$是$^1p_1 $和$^5p_1 $ $ $ $ cq \ bar {c} \ bar {q} $ tetraquark state的混合。此外,我们还能够预测辐射衰减宽度$γ_ {(ψ\ rightarrow j/ψγ)} $,轻骨衰变宽度$γ_{e^+e^ - } $ andronic衰减$ 1^{ - }
In the diquark-diantiquark composition, we study the masses of hidden charm tetraquark systems ($cq\bar{c}\bar{q}$, $cs\bar{c}\bar{s}$ and $cs\bar{c}\bar{q}$) using a linear confinement potential. In this study, we have factorized the four body system into three subsequent two body systems. To remove degeneracy in the S and P wave masses of mesons and tetraquark states, the spin-spin, spin orbit and tensor components of the confined one gluon exchange interactions are employed. In this attempt, we have been able to assign the $ψ(4230)$ as pure $cq\bar{c}\bar{q}$ tetraquark state. $ψ(4360)$ and $ψ(4390)$ as pure $cs\bar{c}\bar{q}$ tetraquark states. According to our analysis $ψ(4260)$ is an admixture of $^1P_1$ and $^5P_1$ $cq\bar{c}\bar{q}$ tetraquark state. Additionally, we have been able to predict the radiative decay width $Γ_{(ψ\rightarrow J/ψγ)}$, leptonic decay width $Γ_{e^+e^-}$ and hadronic decays of $1^{--}$ tetraquark stat
