论文摘要
我们计算了双重厚的旋转 - $ \ frac {3} {2} $ baryons $ baryons $ξ^*_ {qq} $和$ω^*_ {qq} $，带有$ q $和$ q'$ c $ c $ c $或$ b $ quark y Mane-cone jc q cone q cone q cone q cone qcone。定义这些顶点的矩阵元素由四个耦合常数$ g_1 $，$ g_2 $，$ g_3 $和$ g_4 $描述。来自双重繁重的自旋 - $ \ frac {1} {2} $ baryons的不必要污染是通过特殊订购狄拉克矩阵的特殊订购以及选择适当的洛伦兹结构的。强耦合常数是基本参数，可携带有关HADRONIC多重相互作用的性质的信息。对这些参数的研究可能有助于物理学家在双重重的重子和光载体介子中建立强大的潜力。强耦合常数获得的值也可能有助于实验组，分析在各种强子山脉处产生的数据。
We calculate the strong coupling constants among the doubly heavy spin-$ \frac{3}{2} $ baryons $Ξ^*_{QQ}$ and $Ω^*_{QQ}$, 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.
