Discovery potentials of double-charm tetraquarks *

Abstract

In this study, we investigate the discovery potential of double-charm tetraquarks T4.6.4.6.1. We find that their production cross sections at the LHCb with root s = 13 TeV reach 0(104) pb, which indicates that the LHCb has collected 0(108) such particles. Through the decay channels of T[lc1 > D+K-m+ or D D'y (if stable) or TIcci] > DOD' > D D 7r+ (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.
