Özet
The suppression of the individual states in PbPb collisions with respect to their yields in data has been measured. The PbPb and data sets used in the analysis correspond to integrated luminosities of and , respectively, collected in 2011 by the CMS experiment at the LHC, at a center-of-mass energy per nucleon pair of 2.76 TeV. The yields are measured from the dimuon invariant mass spectra. The suppression of the yields in PbPb relative to the yields in , scaled by the number of nucleon-nucleon collisions, , is measured as a function of the collision centrality. Integrated over centrality, the values are , , and lower than 0.10 (at 95% confidence level), for the , , and states, respectively. The results demonstrate the sequential suppression of the states in PbPb collisions at LHC energies.
