J$\psi$ nuclear modification factor at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{NN}}=$2.76 TeV

Ionut-Cristian Arsene

We report on the J$\psi$ nuclear modification factor $R_{\mathrm{AA}}$ at mid-rapidity ($|y|<0.9$) in Pb-Pb collisions at $\sqrt{s_{NN}}=$2.76 TeV measured by ALICE. J$\psi$ candidates are re…
