dc.description.abstractThe first measurement of $phi$-meson production in p-Pb collisions at a nucleon-nucleon centre-of-mass energy $sqrt{s_{rm NN}}$ = 5.02 TeV has been performed with the ALICE apparatus at the LHC. The $phi$-mesons have been identified in the dimuon decay channel in the transverse momentum ($p_{rm T}$) range $1 < p_{rm T} < 7$ 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. Differential cross sections as a function of transverse momentum and rapidity are presented. The forward-backward asymmetry for $phi$-meson production is measured for $2.96< </td><td>y </td><td><3.53$, resulting in a factor $sim 0.5$ with no significant $p_{rm T}$ dependence within the uncertainties. The $p_{rm T}$ dependence of the $phi$ nuclear modification factor $R_{rm pPb}$ exhibits an enhancement up to a factor 1.6 at $p_{rm T}$ = 3-4 GeV/$c$ in the Pb-going direction. The $p_{rm T}$ dependence of the $phi$-meson cross section in pp collisions at $sqrt{s}$ = 2.76 TeV, which is used to determine a reference for the p-Pb results, is also presented here for $1 < p_{rm T} < 5$ GeV/$c$ and $2.5 <y < 4$.
