Multiplicities and $J\mathrm{/}\psi$ suppression at LHC energies

We present our predictions on multiplicities and $J\mathrm{/}\psi$ 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 $J\mathrm{/}\psi$ suppression increases by a factor 5 to 6 compared to RHIC.
