ϒ(nS) polarizations versus particle multiplicity in pp collisions at s=7 TeV

ϒ(nS) polarizations versus particle multiplicity in pp collisions at s=7 TeV

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...
