    • Principal-component analysis of two-particle azimuthal correlations in PbPb and pPb collisions at CMS 

      Sirunyan, A. M.; Tumasyan, A. R; Adam, Wolfgang; Baarmand, Marc M.; Bhopatkar, Vallary; Colafranceschi, Stefano; Hohlmann, Marcus; Noonan, Daniel; Roy, Tuhin S.; Yumiceva, F. (2017-12-05)
      For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from sNN=2.76TeV PbPb and ...
    • Suppression of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states in PbPb collisions at sNN=2.76TeV 

      Khachatryan, Vardan; Sirunyan, A. M.; Tumasyan, A. R; Baarmand, Marc M.; Bhopatkar, Vallary; Colafranceschi, Stefano; Hohlmann, Marcus; Noonan, Daniel; Roy, Tuhin S.; Yumiceva, F. (2017-07-10)
      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. ...
