Description
The X(6900) resonance, originally discovered by the LHCb collaboration and later confirmed by both ATLAS and CMS experiments, has sparked broad interests in the fully-charmed tetraquark states. Relative to the mass spectra and decay properties of fully-heavy tetraquarks, our knowledge
on their production mechanism is still rather limited. In this talk, I will discuss the production of S-wave fully-heavy tetraquark at the LHC and electron-ion collider with the nonrelativistic QCD (NRQCD) framework. We predicted the differential pT spectra of various fully-charmed S-wave tetraquarks at the LHC, and compare with the results predicted from the fragmentation mechanism at large pT end. We also looked at the production prospects at various electron-proton colliders.
