Abstract: Measurements are presented of differential top quark pair ($\mathrm{t \bar t}$) production cross sections using events containing two leptons produced in proton-proton collisions at a centre-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the CERN LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. The differential cross sections are presented as functions of kinematic observables of the top quarks and their decay products, the $\mathrm{t \bar t}$ system, and the total number of jets in the event. The differential cross sections are defined both with particle-level objects in a fiducial phase space close to that of the detector acceptance and with parton-level top quarks in the full phase space. All results are compared with standard model predictions from Monte Carlo simulations with next-to-leading-order (NLO) accuracy in quantum chromodynamics (QCD) at matrix-element level interfaced to parton-shower simulations. Where possible, parton-level results are compared to calculations with beyond NLO precision in QCD. Significant disagreement is observed between data and predictions for numerous observables. The measurements are used to constrain the top quark chromomagnetic dipole moment in an effective field theory framework at NLO in QCD and to extract $\mathrm{t \bar t}$ and leptonic charge asymmetries. | ||

Summary |
Measurements are presented of absolute and normalised differential cross sections of $ \mathrm{t\bar{t}} $ production based on both particle-level objects in a fiducial phase space and parton-level top quarks in a full phase space using pp collisions at a centre-of-mass energy of 13 TeV recorded by the CMS detector. Most measured differential cross sections are well modelled by theoretical predictions. However, significant disagreement between the data and next-to-leading-order Monte Carlo is observed for the transverse momentum of top quarks, leptons, b jets, and $ \mathrm{t\bar{t}} $, $ {\text{l}\bar{\text{l}}} $, and $ \mathrm{b\bar{b}} $ systems and for the invariant mass of the $ \mathrm{t\bar{t}} $, $ {\text{l}\bar{\text{l}}} $, and $ \mathrm{b\bar{b}} $ systems. Similar levels of disagreement are observed for predictions with beyond NLO precision. The jet multiplicity distribution is not well described by any of the next-leading-order Monte Carlo predictions for high multiplicities with the exception of a prediction based on MG5\_aMC@NLO and Pythia8. The absolute particle-level differential cross section as a function of $\Delta\phi$(l,${\bar{\text{l}}}$) is used to constrain the top quark chromomagnetic dipole moment at next-to-leading order in quantum chromodynamics using an effective field theory framework. The normalised differential cross sections as a function of $\Delta|\text{y}|$(t,${\bar{\text{t}}}$) and $\Delta|\eta|$(l,${\bar{\text{l}}}$) are used to measure the $ \mathrm{t\bar{t}} $ and leptonic charge asymmetries for the first time using 13 TeV data. |
