Measurement of the Y(nS) polarizations in pp collisions at √s=7 and 8 TeV. J. High Energ. Phys. 2017, 110 (2017). https://doi.org/10.1007/JHEP12(2017)1101029-8479http://hdl.handle.net/10347/22654The polarization of the Y(1S), Y(2S) and Y(3S) mesons, produced in pp collisions at centre-of-mass energies √s=7 and 8 TeV, is measured using data samples collected by the LHCb experiment, corresponding to integrated luminosities of 1 and 2 fb−1, respectively. The measurements are performed in three polarization frames, using Y → μμ decays in the kinematic region of the transverse momentum p ΥT < 30 GeV/c and rapidity 2.2 < yY < 4.5. No large polarization is observed.eng© CERN, for the bene t of the LHCb Collaboration. Article funded by SCOAP3.
