Abstract

The cross-section for inclusive Phi meson production in pp collisions at a centre-of-mass energy of sqrt(s) = 7 TeV has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section is measured as a function of the Phi transverse momentum pT and rapidity y in the region 0.6 < pT < 5.0 GeV / c and 2.44 < y < 4.06 . The cross-section for inclusive Phi production in this kinematic range is sigma (p p → Phi X ) = 1758 ± 19 (stat) − 14 + 43 (syst) ± 182 (scale) microbarn, where the first systematic uncertainty depends on the pT and y region and the second is related to the overall scale. Predictions based on the Pythia 6.4 generator underestimate the cross-section.
