| Özet |
| A comparison of the relative yields of resonances in the decay channel in Pb-Pb and collisions at a center-of-mass energy per nucleon pair of 2.76 TeV is performed with data collected with the CMS detector at the LHC. Using muons of transverse momentum above and pseudorapidity below 2.4, the double ratio of the and excited states to the ground state in Pb-Pb and collisions, [Υ(2S+3S)/Υ(1S)]Pb-Pb/[Υ(2S+3S)/Υ(1S)]pp, is found to be . The probability to obtain the measured value, or lower, if the true double ratio is unity, is calculated to be less than 1%. |
