| 摘要: | 摘要： (ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Normalised differential top-quark-pair production cross sections are measured in pp collisions at a centre-of-mass energy of 7 TeVat the LHC with the CMS detector using data recorded in 2011 corresponding to an integrated luminosity of 5.0 fb^sup -1^. The measurements are performed in the lepton+jets decay channels (e+jets and [mu]+jets) and the dilepton decay channels (..., [mu] ^sup +^ [mu] ^sup -^, and [mu] ^sup ±^e^sup ^). The ... differential cross section is measured as a function of kinematic properties of the final-state charged leptons and jets associated to b quarks, as well as those of the top quarks and the ... system. The data are compared with several predictions from perturbative QCD calculations up to approximate next-to-next-to-leading-order precision. No significant deviations from the standard model are observed.
