چکیده

We investigate the production of fully - heavy tetraquark states $T_{4Q}$ in $\gamma \gamma$ interactions present proton-proton, proton-nucleus and nucleus-nucleus collisions at CERN Large Hadron Collider (LHC). focus on \gamma \rightarrow {\cal{Q}}{\cal{Q}}$ (${\cal{Q}} = J/\psi,\, \Upsilon$) subprocess, mediated by resonance $s$ channel, predictions for hadronic cross sections considering kinematical ranges probed ALICE LHCb Collaborations. Our results demonstrate that experimental study this process is feasible can be used to existence properties $T_{4c}(6900)$ $T_{4b}(19000)$ states.

Secondary Charmonium Production in Heavy Ion Collisions at LHC Energy

We consider the production of charmonium by DD̄ annihilation during the mixed and hadronic phase of a Pb-Pb collision at LHC energy. The calculations for secondary J/ψ and ψ production are performed within a kinetic model taking into account the spacetime evolution of a longitudinally and transversely expanding medium. It is shown that the yield of secondary J/ψ mesons depends strongly on the J/...

Inclusive Heavy-quarkonium Production in Hadronic Collisions∗

We discuss the theory of inclusive production of heavy quarkonium, the comparison between theory and experiment, and the expected nuclear effects in cold nuclear targets. We also present predictions, based on Nonrelativistic QCD (NRQCD), for quarkonium production cross sections in the LHC energy range. We find that nuclear effects in the production cross sections are largely independent of the ...

Heavy quarkonium production in hadronic collisions

Different theoretical models which attempt to describe hadronic production of heavy quarkonia are reviewed. Firstly, we consider the Color Singlet Model and point out the large discrepancies between the theoretical predictions and the results from the Tevatron detectors. Then some other models are introduced, quickly discussed and confronted with experimental results. Finally, we suggest possib...
