dc.description.abstractA comparison of the relative yields of resonances in the þ decay channel in Pb-Pb and pp 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 4 GeV=c and pseudorapidity below 2.4, the double ratio of the ð2SÞ and ð3SÞ excited states to the ð1SÞ ground state in Pb-Pb and pp collisions, ½ ð2S þ 3SÞ= ð1SÞPb-Pb=½ ð2S þ 3SÞ= ð1SÞpp, is found to be 0:31þ0:19 0:15ðstatÞ 0:03ðsystÞ. The probability to obtain the measured value, or lower, if the true double ratio is unity, is calculated to be less than 1%.en_US
