Centrality and transverse momentum dependent suppression of $$\Upsilon (1S)$$ Υ ( 1 S ) and $$\Upsilon (2S)$$ Υ ( 2 S ) in p–Pb and Pb–Pb collisions at the CERN Large Hadron Collider

摘要: Deconfined QCD matter in heavy-ion collisions has been a topic of paramount interest for many years. Quarkonia suppression at the relativistic Heavy Ion Collider (RHIC) and Large Hadron (LHC) experiments indicate quark-gluon plasma (QGP) formation such collisions. Recent LHC have given indications hot effect asymmetric p–Pb nuclear Here, we employ theoretical model to investigate bottomonium Pb–Pb $$\sqrt{s_{NN}}=2.76$$ , 5.02 TeV, $$\sqrt{s_{NN}}=5.02$$ TeV center-of-mass energies under QGP scenario. Our present formulation is based on an unified consisting due color screening, gluonic dissociation along with collisional damping. Regeneration correlated $$Q\bar{Q}$$ pairs also taken into account current work. We obtain here net terms survival probability combined plus regeneration deconfined medium. mainly concentrate centrality, $$N_\text {part}$$ transverse momentum, $$p_{T}$$ dependence $$\Upsilon (1S)$$ $$ \Upsilon (2S)$$ states mid-rapidity. compare our predictions corresponding experimental data obtained energies. find that observations $$p_t$$ dependent agree reasonably well predictions.
