The cross-section for inclusive mlns="""">? meson production in mlns="""">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 mlns="""">? transverse momentum and rapidity mlns="""">y in the region and . The cross-section for inclusive mlns="""">? production in this kinematic range is , where the first systematic uncertainty depends on the and mlns="""">y region and the second is related to the overall scale. Predictions based on the Pythia 6.4 generator underestimate the cross-section.
