Measurement of the differential cross section for top-quark-pair production in the dilepton channel at √s = 13 TeV with the CMS detector — •Mykola Savitskyi, Till Arndt, Carmen Diez Pardos, Alexander Grohsjean, Ali Harb, Johannes Hauk, James Keaveney, and Maria Aldaya — Deutsches Elektronen-Synchrotron (DESY), Notkestrasse 85, D-22607 Hamburg

Measurements of differential top-quark-pair (tt) production cross sections are performed using final states with two leptons (e⁺e⁻, µ⁺µ⁻, and e^±µ^∓) in proton-proton collisions at √s = 13 TeV at the CERN LHC. The data were recorded with the CMS detector. The tt production cross section is measured as a function of kinematic properties of the top quarks and the tt system, as well as of the top quark decay products. The measurements are confronted with several modern Monte Carlo predictions, and are also compared with different perturbative QCD calculations of beyond-NLO accuracy.
