Abstract
$$\phi $$ ϕ meson measurements provide insight into strangeness production, which is one of the key observables for the hot medium formed in high-energy heavy-ion collisions. ALICE measured $$\phi $$ ϕ production through its decay in muon pairs in Pb–Pb collisions at $$\sqrt{s_\mathrm {NN}} = 2.76$$ sNN=2.76 TeV in the intermediate transverse momentum range $$2< p_\mathrm {T}< 5$$ 2<pT<5 GeV/c and in the rapidity interval $$2.5<y<4$$ 2.5<y<4 . The $$\phi $$ ϕ yield was measured as a function of the transverse momentum and collision centrality. The nuclear modification factor was obtained as a function of the average number of participating nucleons. Results were compared with the ones obtained via the kaon decay channel in the same $$p_\mathrm {T}$$ pT range at midrapidity. The values of the nuclear modification factor in the two rapidity regions are in agreement within uncertainties.
