Multiplicities and $J/\psi$ suppression at LHC energies

TL;DR

This paper predicts particle multiplicities and J/psi suppression at LHC energies, considering shadowing and hot medium effects, indicating significant suppression and high multiplicity compared to RHIC.

Contribution

It introduces a model that incorporates initial shadowing and final state interactions to predict multiplicities and J/psi suppression at LHC energies.

Findings

1800 charged particles predicted at LHC

J/psi suppression increases by a factor of 5-6 compared to RHIC

Results highlight the importance of shadowing and hot medium effects

Abstract

We present our predictions on multiplicities and $J/\psi$ suppression at LHC energies. Our results take into account shadowing effects in the initial state and final state interactions with the hot medium. We obtain 1800 charged particles at LHC and the $J/\psi$ suppression increases by a factor 5 to 6 compared to RHIC.
