Abstract

The normalized differential cross section for top quark pair (tt ¯
tt¯
) production is measured in pp collisions at a centre-of-mass energy of 8TeV
TeV
at the CERN LHC using the CMS detector in data corresponding to an integrated luminosity of 19.7fb −1
fb−1
. The measurements are performed in the lepton+
+
jets (e/μ
e/μ
+
+
jets) and in the dilepton (e + e −
e+e−
, μ + μ −
μ+μ−
, and e ± μ ∓
e±μ∓
) decay channels. The tt ¯
tt¯
cross section is measured as a function of the kinematic properties of the charged leptons, the jets associated to b quarks, the top quarks, and the tt ¯
tt¯
system. The data are compared with several predictions from perturbative quantum chromodynamic up to approximate next-to-next-to-leading-order precision. No significant deviations are observed relative to the standard model predictions.
