      abstract     = {The 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=7 TeV . The
                      measurements are performed with a dimuon data sample
                      collected in 2011 by the CMS experiment, corresponding to an
                      integrated luminosity of 4.9 fb −1 . The results are
                      extracted from the dimuon decay angular distributions, in
                      two ranges of ϒ(nS) transverse momentum (10–15 and
                      15–35 GeV), 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.},
