Abstract:

Measurements of normalized differential top quark pair (

\mathrm{t \bar t}

) production cross sections in proton-proton collisions at a centre-of-mass energy of 13 TeV at the CERN LHC are presented. The data were recorded in 2015 with the CMS detector and correspond to an integrated luminosity of

2.2~\mathrm{fb^{-1}}

. The measurements are performed in the dilepton decay channels (

\mathrm{e^+e^-}

,

\mu^+\mu^-

, and

\mu^{\pm} \mathrm{e^{\mp}}

). The

\mathrm{t \bar t}

production cross section is measured as a function of kinematics of the top quarks, the

\mathrm{t \bar t}

system, and of the number of jets in the event. The results are compared with several perturbative QCD calculations and are found to be broadly in agreement with the predictions.
