1201.5069 (CMS Collaboration)

Suppression of non-prompt J/psi, prompt J/psi, and Y(1S) in PbPb
collisions at sqrt(sNN) = 2.76 TeV

CMS Collaboration
Yields of prompt and non-prompt J/psi, as well as Y(1S) mesons, are measured by the CMS experiment via their dimuon decays in PbPb and pp collisions at sqrt(sNN) = 2.76 TeV for quarkonium rapidity |y|<2.4. Differential cross sections and nuclear modification factors are reported as functions of y and transverse momentum pt, as well as collision centrality. For prompt J/psi with relatively high pt (6.5View original: http://arxiv.org/abs/1201.5069
