Abstract (data abstract)
CERN-LHC. Measurement of the polarizations of the Upsilon(1S),(2S) and (3S) from their decay into two muons in proton-proton collisions at a centre of mass energy of 7 TeV using data with a total integrated luminosity of 4.9 fb-1. Data are presented on the Lambda (Theta, Phi and Theta-Phi) parameters of the di-muon angular distributions where Theta and Phi are the polar and azimuthal angles, respectively, of the positive muon with respect to the Z axis of the chosen polarization frame. Three frames are used, the Collins-Soper (CS) frame, the centre-of-mass Helicity (HX) frame and the perpendicular Helicity (PX) frame, orthogonal to the CS frame. Data are also given for the frame-invariant quantity, Lambda(Tilde). The data are presented as a function of the PT of the Upsilon in two rapidity regions. The tables show the results with total uncertainties (reflecting statistical and systematic effects) for 3 different Confidence Levels (68.3%, 95.5% and 99.7%). The last column, for comparison, gives the results only considering statistical uncertainties (at 68.3%) The final 3 tables show the estimated number of signal events for each Upsilon state.
