CERN-LHC. Measurement of the cross sections for Upsilon(1s), Upsilon(2S) and Upsilon(3S) production in proton-proton collisions at a centre of mass energy of 7 TeV. The data sample, with an integrated luminosity of 35.8+-1.4 pb-1 covers the PT range 0-50 GeV/c and |rapidity| < 2.4. The Upsilon resonances are identified through their decay to di-muons and the data are uncorrected for the branching ratio. Fiducial as well as acceptance-corrected cross sections are tabulated. The effects of the polarization on the acceptance corrected cross section are given for the following extreme scenarios:
HX_ T - fully transverse in the helicity frame
HX_ L - fully longitudinal in the helicity frame
CS_ T - fully transverse in the Collins-Soper frame
CS_ L - fully longitudinal in the Collins-Soper frame.
