CERN-LHC. Measurements of the production cross sections for Upsilon 1S, 2S and 3S mesons in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample used has an integrated luminosity of 1.8 fb-1 collected between March and August 2011. The data cover the Upsilon |y| region 0-2.25 and PT < 70 GeV/c. The data are given assuming unpolarized Upsilon production. Acceptance weights are also given in the link below for the effects of different polarization scenarios.
