JHJohannes HesslerMax Planck Computing and Data Facility

Key Points

The aim is to summarize recent measurements of differential top quark cross sections by ATLAS and CMS experiments.
Conducted measurements of top quark pair production and single (anti-)top quark production.
Analyzed the interference with other Standard Model processes.
Compared measured data with state-of-the-art theoretical predictions.
No single theory model successfully describes all data bins.
Higher-order perturbative quantum chromo dynamics predictions show an improved fit to the data.

Abstract

This report summarizes recent results of differential top quark cross section measurements performed by the ATLAS and CMS experiments. The production of a pair of top quarks is studied as well as the single (anti-)top quark production and the interference with other Standard Model (SM) processes with the same final state. State-of-the-art theory predictions are compared to the data. No theory model is able to describe the data across all bins, but an improved description of the data when moving to predictions in higher orders in perturbative Quantum Chromo Dynamics (QCD) can be observed.
