The strong coupling constants among hadronic multiplets, as fundamental parameters, carry information on the nature of strong interaction among the 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 Ξcc state by LHCb, we determine the strong coupling constants among the doubly heavy spin-1/2 baryons, Ξ(′)QQ, Ω(′)QQ and light pseudoscalar mesons, π, K , η and η′ within the framework of the light cone QCD sum rules. The obtained results may help experimental groups in analyses of the related data at hadron colliders.
