ϒ suppression at forward rapidity in Pb–Pb collisions at

Inclusive ϒ(1S) and ϒ(2S) production have been measured in Pb–Pb collisions at the centre-of-mass energy per nucleon–nucleon pair $\sqrt{{s}_{\mathrm{NN}}}=5.02$ TeV, using the ALICE detector at the CERN LHC. The ϒ mesons are reconstructed in the centre-of-mass rapidity interval $2.5
