Örnek Metin	The relative modification of the prompt ψð2SÞ and J=ψ yields from pp to PbPb collisions, at the centerof-mass energy of 5.02 TeV per nucleon pair, is presented. The analysis is based on pp and PbPb data samples collected by the CMS experiment at the LHC in 2015, corresponding to integrated luminosities of 28.0 pb−1 and 464 μb−1, respectively. The double ratio of measured yields of prompt charmonia reconstructed through their decays into muon pairs, ðNψð2SÞ=NJ=ψ ÞPbPb=ðNψð2SÞ=NJ=ψ Þpp, is determined as a function of PbPb collision centrality and charmonium transverse momentum pT, in two kinematic intervals: jyj < 1.6 covering 6.5 < pT < 30 GeV=c and 1.6 < jyj < 2.4 covering 3 < pT < 30 GeV=c. The centrality-integrated double ratios are 0.36 0.08ðstatÞ 0.05ðsystÞ in the first interval and 0.24 0.22ðstatÞ 0.09ðsystÞ in the second. The double ratio is lower than unity in all the measured bins, suggesting that the ψð2SÞ yield is more suppressed than the J=ψ yield in the explored phase space.
