φ meson production at forward rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

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 colli- sions. ALICE measured φ production through its decay in muon pairs in Pb–Pb collisions at √sNN = 2.76 TeV in the intermediate transverse momentum range 2 < pT < 5 GeV/c and in the rapidity interval 2.5 < y < 4. The φ yield was measured as a function of the transverse momen- tum and collision centrality. The nuclear modification factor was obtained as a function of the average number of par- ticipating nucleons. Results were compared wit ...Daha fazlası
