The strong coupling constants of hadronic multiplets are fundamental parameters which carry information about 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 state by LHCb, we determine the strong coupling constants among the doubly heavy spin-1/2 baryons, , and light pseudoscalar mesons, , K, and 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.

双重自旋1/2重子与轻伪标量介子的强耦合常数

强子多重态的强耦合常数是携带参与粒子之间强相互作用信息的基本参数。这些参数可以帮助我们构建强子-强子强势，并获得有关强子结构的信息。受最近 LHCb 对双魅态的观察的启发，我们在轻锥 QCD 和规则的框架内确定了双重自旋 1/2 重子和轻伪标量介子 , K之间的强耦合常数. 所得结果可能有助于实验组对强子对撞机相关数据的分析。
