Figure 3

$\phi$-meson cross section in p-Pb collisions at $\snn = 5.02$ TeV as a function of $\pt$ in the backward (left) and forward (right) rapidity regions. Error bars (smaller than the markers) and boxes represent statistical and systematic uncertainties, respectively. Predictions by HIJING and DPMJET are also shown, together with the result of a fit with the Levy-Tsallis function (Eq. 1).
