DESCRIPTION:Speakers: Captain Rituraj Singh (Birla Institute of Technology
  and Science\, Pilani)\nProton–proton ( pp) collision has been considere
 d a baseline to understand the formation of the primordial matter\, the qu
 ark-gluon plasma in relativistic heavy-ion (AA) collisions. However\, rece
 nt experimental findings show QGP-like phenomena in ultra-relativistic (Te
 V) pp collisions. Such findings require a cautious study of the system pro
 duced in pp collisions at relativistic energies. In this work\, we investi
 gate the charmonium production in pp collisions at $\\sqrt{s} $= 5.02\, 7 
 and 13 TeV energies. Further\, we obtain net charmonia yield at various ev
 ent multiplicities using our UMQS model\, which includes color screening\,
  gluonic dissociation\, collisional damping\, and regeneration mechanisms.
  Using the UMQS model\, we try to explain the normalized $J/\\psi$ yield a
 gainst the normalized charged multiplicity and compare it with the data av
 ailable for 7 and 13 TeV pp collisions. Here we obtain a net suppression o
 f charmonia at high-multiplicity events\, indicating the possible existenc
 e of quark-gluon plasma in pp collisions. Details of the model ingredients
 \, method of analysis\, and important results will be discussed.\n\nhttps:
