摘要

The strong coupling constants of hadronic multiplets are fundamental parameters which carry informa-tion 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 ob-servation of the doubly charmed Ecc state by LHCb,we determine the strong coupling constants among the doubly heavy spin-1/2 baryons,(E)QQ('),,Ω and light pseudoscalar mesons,n,K,η and η'within the framework of the light cone QCD sum rules.The obtained results may help experimental groups in analysis of the related data at had-ron colliders.
