The ratio between the prompt psi(2S) and J/psi yields, reconstructed via their decays into muon pairs, is measured in lead-lead and proton-proton collisions at a centre-of-mass energy per nucleon-nucleon pair of 2.76 TeV. The analysis is based on lead-lead and proton-proton data samples collected by CMS at the LHC, corresponding to integrated luminosities of 150 mub^-1 and 5.4 pb^-1, respectively. The double ratio of measured yields, $(N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{\\mathrm{PbPb}} / (N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{pp}$, is computed in three lead-lead collision centrality bins and two kinematic ranges: one at midrapidity, |y|<1.6, covering the transverse momentum range 6.5<pT<30 GeV/c, and the other at forward rapidity, 1.6<|y|<2.4, extending to lower pT values, 3<pT<30 GeV/c. The centrality-integrated double ratio changes from 0.45 +/- 0.13 (stat) +/- 0.07 (syst) in the first range to 1.67 +- 0.34 (stat) +- 0.27 (syst) in the second. This difference is most pronounced in the most central collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66548.v1/t1","@type":"Dataset","description":"Double ratio of measured yields, $(N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{\\mathrm{PbPb}} / (N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{pp}$, as a function of centrality, for the midrapidity...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66548.v1/t2","@type":"Dataset","description":"Double ratio of measured yields, $(N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{\\mathrm{PbPb}} / (N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{pp}$, as a function of centrality, for the forward...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66548.v1/t3","@type":"Dataset","description":"Double ratio of measured yields, $(N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{\\mathrm{PbPb}} / (N_{\\psi\\mathrm{(2S)}} / N_{J/\\psi})_{pp}$, integrated over centrality, for the midrapidity and forward...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.66548.v1/t4","@type":"Dataset","description":"Nuclear modification factor RAA of psi(2S) integrated over centrality, for the midrapidity and forward rapidity analysis bins.","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1320775?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/66548"}],"inLanguage":"en","name":"Measurement of prompt psi(2S) to J/psi yield ratios in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1320775?version=1","version":1}
