Fully - heavy tetraquark production by $\gamma\gamma$ interactions in hadronic collisions at the LHC
We investigate the production of the fully - heavy tetraquark states T4Q in the γγ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC). We focus on the γγ→QQ ( Q=J/ψ,ϒ ) subprocess, mediated by the T4Q resonance in the s - chan...

| description | We investigate the production of the fully - heavy tetraquark states T4Q in the γγ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC). We focus on the γγ→QQ ( Q=J/ψ,ϒ ) subprocess, mediated by the T4Q resonance in the s - channel, and present predictions for the hadronic cross sections considering the kinematical ranges probed by the ALICE and LHCb Collaborations. Our results demonstrate that the experimental study of this process can be used to investigate the existence and properties of the T4Q states. |

We focus on the $\gamma \gamma \rightarrow {\cal{Q}}{\cal{Q}}$ (${\cal{Q}} = J/\psi,\, \Upsilon$) subprocess, mediated by the $T_{4Q}$ resonance in the $s$ - channel, and present predictions for the hadronic cross sections considering the kinematical ranges probed by the ALICE and LHCb Collaborations. Our results demonstrate that the experimental study of this process is feasible and can be used to investigate the existence and properties of the $T_{4c}(6900)$ and $T_{4b}(19000)$ states.arXiv:2101.03798oai:cds.cern.ch:27610592021-01-11 |
