Event activity dependence of $ Y $ (nS) production in $ \sqrt{{{s_{NN }}}} $ = 5.02 TeV pPb and $ \sqrt{s} $ = 2.76 TeV pp collisions

Event activity dependence of $ Y $ (nS) production in $ \sqrt{{{s_{NN }}}} $ = 5.02 TeV pPb and $ \sqrt{s} $ = 2.76 TeV pp collisions

The production of Y(1S), Y(2S), and Y(3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities of about 31 inverse nanobarns (pPb) and 5.4 inverse picobarns (pp), collected in 2...

Zusammenfassung:The production of Y(1S), Y(2S), and Y(3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities of about 31 inverse nanobarns (pPb) and 5.4 inverse picobarns (pp), collected in 2013 by the CMS experiment at the LHC. Upsilons that decay into muons are reconstructed within the rapidity interval abs(y[CM])
