    Paper, Journal Article

    State-of-the-art theoretical predictions accurate to next-to-leading order QCD interfaced with {\sc pythia} and {\sc herwig} are tested by comparing the unfolded \(t\bar{t}\) differential data collected with the CMS detector at 8 TeV and 13 TeV. These predictions are also compared with the measurements of underlying event activity distributions accompanying \({\rm t\bar{t}}\) events. Furthermore, predictions of beyond NLO accuracy in QCD are compared with the data.
