ϕ-Meson production at forward rapidity in p–Pb collisions at √sNN = 5.02 TeV and in pp collisions at √s = 2.76 TeV

The first study of ϕ -meson production in p–Pb collisions at forward and backward rapidity, at a nucleon–nucleon centre-of-mass energy sNN=5.02 TeV , has been performed with the ALICE apparatus at the LHC. The ϕ -mesons have been identified in the dimuon decay channel in the transverse momentum ( pT ) range 1 < pT < 7 GeV/c , both in the p-going ( 2.03<y<3.53 ) and the Pb-going ( −4.46<y<−2.96 ) directions — where y stands for the rapidity in the nucleon– nucleon centre-of-mass — the integrated luminosity amounting to 5.01±0.19 nb−1 and 5.81±0.20 nb−1 , respectively, for the two data samples. Differential cross sections as a function of transverse momentum and rapidity are presented. The forward–backward ratio for ϕ -meson production is measured for 2.96 < |y| < 3.53 , resulting in a ratio ∼0.5 with no significant pT dependence within the uncertainties. The pT dependence of the ϕ nuclear modification factor RpPb exhibits an enhancement up to a factor 1.6 at pT=3–4 GeV/c in the Pb-going direction. The pT dependence of the ϕ -meson cross section in pp collisions at s=2.76 TeV , which is used to determine a reference for the p–Pb results, is also presented here for 1<pT<5 GeV/c and 2.5 < y < 4 , for a 78±3 nb−1 integrated luminosity sample.
