摘　　要：In this study,we investigate the discovery potential of double-charm tetraquarks■.We find that their production cross sections at the LHCb with■TeV reach O(10^(4))pb,which indicates that the LHCb has collected O(10^(8))such particles.Through the decay channels of■or■or■(if unstable),it is highly expected that they get discovered at the LHCb in the near future.We also discuss the productions and decays of the double-charm tetraquarks at future Tera-Z factories.
