Absolute and normalised differential top quark pair production cross sections are measured in the dilepton decay channels. The differential cross sections have been obtained by the CMS experiment at the CERN LHC in 2016 in proton-proton collisions at a centre-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 35.9/fb. The cross sections are measured differentially as a function of the kinematic properties of the top quarks and the tt system at the particle and parton levels, and the top quark decay products at the particle level. The results are compared to Monte Carlo simulations from POWHEG interfaced with the parton shower generators PYTHIA 8 and HERWIG 7 up to NNLO (next-to-next leading order) accuracy.
