报告摘要：

Human exploration into the deeplevel structure of matter has undergone a long and arduous journey that is still ongoing. In 2020, the LHCb experiment reported the first observation of X(6900) in the invariant mass spectrum of J/ψ-pair, which was later supported by ATLAS and CMS data, along with the discovery of new exotic structures. This report will present studies on the production and decay processes of fullycharmed tetraquark states at hadron colliders, including calculations based on nonrelativistic QCD (NRQCD) effective theory for the production and differential cross sections of fullycharmed tetraquark states, corrections from relevant soft gluon radiation effects, as well as angular distributions and quantum entanglement effects in the cascade decays of fullycharmed tetraquark states. The aim is to carry out a detailed and indepth investigation of the exotic structures observed in the invariant mass spectrum of J/ψ-pair.
