Figure 4

 $\phi$-meson cross section in p-Pb collisions at $\snn = 5.02$ TeV as a function of rapidity, integrated over the range $1 < \pt < 7$ GeV/$c$. Error bars and boxes represent statistical and systematic uncertainties, respectively. Predictions by HIJING and DPMJET are also shown, together with the mid-rapidity data point from the $\phi$-meson measurement in the K$^+$K$^-$ channel, also evaluated in the range $1 < \pt < 7$ GeV/$c$.
