The production yields of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 TeV. The data correspond to integrated …

The Υ (1S), Υ (2S), and Υ (3S) production cross sections are measured using a data sample corresponding to an integrated luminosity of 35.8 ± 1.4 pb -1 of proton-proton collisions at √ s = 7 TeV, collected with the CMS detector …
