The double-differential cross sections of promptly produced J/psi and psi(2S) mesons are measured in proton-proton collisions at sqrt(s) = 7 TeV, as function of transverse momentum pT and absolute rapidity |y|. The analysis uses J/psi and psi(2S) dimuon samples collected in 2011 by the CMS experiment at the LHC, corresponding to integrated luminosities of 4.55 and 4.9 fb^-1, respectively. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and extend to pT = 120 and 100 GeV for the J/psi and psi(2S), respectively, when integrated over the interval |y| < 1.2. The ratio of the psi(2S) over J/psi cross sections is also reported for |y| < 1.2, over the range 10 < pT < 100 GeV. These are the highest-pT values for which the cross sections and ratios have been measured.\n\nThe tables below list the results of J/psi and psi(2S) differential cross section times dimuon branching fraction B in four rapidity bins for the unpolarized scenario, the unpolarized differential cross sections times B in the integrated rapidity range |y| < 1.2 with the corresponding scaling factors needed to obtain the cross sections for different polarization scenarios and the ratio of the psi(2S) to J/psi cross sections for the integrated rapidity range |y| < 1.2.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66886.v1/t1","@type":"Dataset","description":"J/psi double-differential cross section times branching fraction assuming unpolarized production as a function of pT and y for 0.0 <...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66886.v1/t2","@type":"Dataset","description":"psi(2S) double-differential cross section times branching fraction assuming unpolarized production as a function of pT and y for 0.0 <...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66886.v1/t3","@type":"Dataset","description":"J/psi double-differential cross section times branching fraction and the corresponding scaling factors to obtain the cross sections for different polarization...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.66886.v1/t4","@type":"Dataset","description":"psi(2S) double-differential cross section times branching fraction and the corresponding scaling factors to obtain the cross sections for different polarization...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.66886.v1/t5","@type":"Dataset","description":"Ratio of psi(2S) to J/psi differential cross section times branching fractions assuming unpolarized productions as a function of pT for...","name":"Table 5"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1345023?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/66886"}],"inLanguage":"en","name":"Measurement of J/psi and psi(2S) prompt double-differential cross sections in pp collisions at sqrt(s) = 7 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1345023?version=1","version":1}
