标题： Strong interaction of doubly heavy spin-3/2 baryons with light vector mesons

摘要： 我们利用光锥 QCD 和重子$ \frac{3}{2} $、$\Xi^*_{QQ}$和$\Omega^*_{QQ}$（其中$ Q $和$ Q' $分别为$ c$或$ b $夸克）之间的强耦合常数计算了轻矢量介子。 定义这些顶点的矩阵元由四个耦合常数$ g_1$、$ g_2$、$ g_3$和$ g_4 $描述。 来自双重重子自旋-$ \frac{1}{2} $重子的不需要的污染通过狄拉克矩阵的特殊排列和适当的洛伦兹结构选择被消除。 强耦合常数是携带关于强相互作用性质的基本参数。 研究这些参数可能有助于物理学家构建双重重子和轻矢量介子之间的强势。 获得的强耦合常数值也可能有助于实验小组分析各种强子对撞机产生的数据。 显示英文摘要

摘要： We calculate the strong coupling constants among the doubly heavy spin-$ \frac{3}{2} $ baryons $\Xi^*_{QQ}$ and $\Omega^*_{QQ}$, with $ Q $ and $ Q' $ being $ c$ or $ b $ quark, with light vector meson by means of the light-cone QCD sum rules. The matrix elements defining these vertices are described by four coupling constants $ g_1$, $ g_2$, $ g_3$, and $ g_4 $. The unwanted pollution coming from the doubly heavy spin-$ \frac{1}{2} $ baryons are removed by a special ordering of Dirac matrices and selection of appropriate Lorentz structures. The strong coupling constants are basic parameters that carry information on the nature of the strong interaction among hadronic multiplets. Investigation of these parameters may help physicists in the construction of the strong potentials among the doubly heavy baryons and light vector mesons. The values obtained for the strong coupling constants may also help experimental groups in analyses of the data produced at various hadron colliders.
