Abstract Plain Text:
The inclusive \jpsi production in \mbox{Pb-Pb} interactions at the center-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\rm NN}}=5.02$ TeV has been studied using the ALICE detector at the CERN LHC.
The J/$\psi$ meson is detected via its decay to muon pairs in the centre-of-mass rapidity region $2.5<y<4$.
In this Letter, we present results on the nuclear modification factor $R_{\rm AA}$, as a function of the centrality of the collision and, for central collisions, of the transverse momentum $p_{\rm T}$ of the J/$\psi$.
The measured values are compared to previous results obtained by ALICE in \mbox{Pb-Pb} collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV.
The ratio between the $R_{\rm AA}$ obtained at the two energies is also computed and compared to calculations of transport and statistical models.
{\it To be tuned } We find indications for an increase of $R_{\rm AA}$ with $\sqrt{s_{\rm NN}}$ by about 10\%, from peripheral  to central collisions.
In central events, as a function of $p_{\rm T}$, the increase of $R_{\rm AA}$ with $\sqrt{s_{\rm NN}}$ is more evident at low $p_{\rm T}$.
A good agreement with theoretical models is found.
