dc.description.abstractThe polarizations of the ϒ(1S), ϒ(2S), and ϒ(3S)mesons are measured as a function of the charged particle multiplicity in proton–proton collisions at √s=7TeV. The measurements are performed with a dimuon data sample collected in 2011 by the CMS experiment, corresponding to an integrated luminosity of 4.9fb−1. The results are extracted from the dimuon decay angular distributions, in two ranges of ϒ(nS)transverse momentum (10–15 and 15–35GeV), and in the rapidity interval |y| <1.2. The results do not show significant changes from low-to high-multiplicity pp collisions, although large uncertainties preclude definite statements in the ϒ(2S)and ϒ(3S)cases.en_US
