| Özet |
| Normalised multi-differential cross sections for top quark pair () production are measured in proton-proton collisions at a centre-of-mass energy of 13 using events containing two oppositely charged leptons. The analysed data were recorded with the CMS detector in 2016 and correspond to an integrated luminosity of . The double-differential cross section is measured as a function of the kinematic properties of the top quark and of the system at parton level in the full phase space. A triple-differential measurement is performed as a function of the invariant mass and rapidity of the system and the multiplicity of additional jets at particle level. The data are compared to predictions of Monte Carlo event generators that complement next-to-leading-order (NLO) quantum chromodynamics (QCD) calculations with parton showers. Together with a fixed-order NLO QCD calculation, the triple-differential measurement is used to extract values of the strong coupling strength and the … |
