Abstract (data abstract)
CERN-LHC. The production of $\Upsilon$ mesons in Pb–Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV is measured with the muon spectrometer of ALICE at the LHC. The yields as well as the nuclear modification factors are determined in the forward rapidity region 2.5 $<y<$ 4.0, as a function of rapidity, transverse momentum and collision centrality. The cross sections in proton–proton collisions at $\sqrt{s}$ = 5.02 TeV used for the determination of the nuclear modification factors are also reported.
