ϕϕ\phi 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 ϕϕ\phi production through its decay in muon pairs in Pb-Pb collisions at sNN−−−√=2.76sNN=2.76\sqrt{s_\mathrm {NN}}...

Description
Summary:ϕϕ\phi 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 ϕϕ\phi production through its decay in muon pairs in Pb-Pb collisions at sNN−−−√=2.76sNN=2.76\sqrt{s_\mathrm {NN}} = 2.76 TeV in the intermediate transverse momentum range 2<pT<52<pT<52< p_\mathrm {T}< 5 GeV/c and in the rapidity interval 2.5<y<42.5<y<42.5<y<4. The ϕϕ\phi 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 pTpTp_\mathrm {T} range at midrapidity. The values of the nuclear modification factor in the two rapidity regions are in agreement within uncertainties.
