Normalised differential top-quark-pair production
cross sections are measured in pp collisions at a centreof-
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−1. The measurements are performed
in the lepton + jets decay channels (e + jets and μ + jets)
and the dilepton decay channels (e+e−, μ
−, and μ
The t¯t 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 t¯t 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.
