The cross-section for inclusive ? meson production in pp collisions at a centre-of-mass energy of has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section is measured as a function of the ? transverse momentum and rapidity y in the region and . The cross-section for inclusive ? production in this kinematic range is , where the first systematic uncertainty depends on the and y region and the second is related to the overall scale. Predictions based on the Pythia 6.4 generator underestimate the cross-section.
