Fit to the tag (left) and the probe (right) sample in the bin $0.6 < p_T < 0.8 {\mathrm{ Ge V /}c} $, $3.34 < y < 3.52$ for one of the two magnet polarities. Shown are the data points, the fit result (thick solid line) as well as the signal (thin solid line) and the background component (dash-dotted line).

Inclusive differential $\phi$ production cross-section as a function of $p_T$ (top) and $ y$ (bottom), measured with data (points), and compared to the LHCb default MC tuning (solid line) and Perugia 0 tuning (dashed line). The error bars represent the statistical uncertainty, the braces show the bin dependent systematic errors, the overall scale uncertainty from Table 1 is not plotted. The lower parts of the plots show the ratio data cross-section over Monte Carlo cross-section. Error bars in the ratio plots show statistical uncertainties only.

Summary of relative systematic uncertainties that are common to all bins.

Binned differential cross-section, in ${\rm \upmu b }/ {\mathrm{ Me V /}c} $, as function of $p_T$ (GeV/c) and $ y$ . The statistical and the bin-dependent systematic uncertainties are quoted. There is an additional bin-independent uncertainty of 10% related to the normalization (Table 1).
