论文摘要
强烈的音激态耦合常数是基本参数，它具有参与粒子之间强相互作用的信息。这些参数可以帮助我们构建强子 - 戴隆强的潜力，并获得有关相关哈隆结构的信息。由LHCB的最新观察到了最新的诱人$ξ_{cc} $状态的动机，我们确定了双重厚度的spin-1/2 baryons之间的强耦合常数，$ξ^{（\ prime）} _ {qq^\ prime}介子，$π$，$ k $，$η$和$η^\ prime $在光锥QCD总规则的框架内。获得的结果可能有助于实验组分析强子山脉相关数据。
The strong coupling constants of hadronic multiplets are fundamental parameters which carry information of the strong interactions among participating particles. These parameters can help us construct the hadron-hadron strong potential and gain information about the structure of the involved hadrons. Motivated by the recent observation of the doubly charmed $Ξ_{cc}$ state by LHCb, we determine the strong coupling constants among the doubly heavy spin-1/2 baryons, $ Ξ^{(\prime)}_{QQ^\prime }$, $ Ω^{(\prime)}_{QQ^\prime}$ and light pseudoscalar mesons, $ π$, $ K $, $η$ and $ η^\prime $ within the framework of the light cone QCD sum rules. The obtained results may help experimental groups in analysis of the related data at hadron colliders.
