Top cross section in dileptonic and semi-leptonic $t\bar{t}$ events.

At the Large Hadron Collider, top quarks are primarily produced in quark-antiquark pairs ($t\bar{t}$), and the prediction of the corresponding inclusive cross-section ($\sigma_{t\bar{t}}$) is a substantial challenge for QCD. Precise measurements of $\sigma_{t\bar{t}} are sensitive to the gluon parto...

description At the Large Hadron Collider, top quarks are primarily produced in quark-antiquark pairs ($t\bar{t}$), and the prediction of the corresponding inclusive cross-section ($\sigma_{t\bar{t}}$) is a substantial challenge for QCD. Precise measurements of $\sigma_{t\bar{t}} are sensitive to the gluon parton distribution function (PDF) of the proton, the strong coupling constant, the top-quark mass, and potential enhancements due to physics beyond the Standard Model. Results are presented for the dilepton and lepton+jets channel at 13 TeV.
