Latest results on differential cross sections as a function of kinematic variables at the LHC and Tevatron

TL;DR

This paper reviews recent measurements of differential top quark pair production cross sections at the LHC and Tevatron, comparing experimental results with advanced QCD predictions at various energies and topologies.

Contribution

It provides the first measurements of differential single top t-channel cross sections in proton-proton collisions at 7 and 8 TeV.

Findings

Measurements agree with perturbative QCD predictions up to approximate NNLO.

Results include boosted topologies and both parton and particle level analyses.

Comparisons with Tevatron data are also presented.

Abstract

An overview of recent measurements of differential top quark pair ($t\bar{t}$) production cross sections is presented, including results in boosted topologies and results both at parton and particle level. The first measurements of differential single top quark t-channel production cross sections in proton-proton collisions are as well presented. The results are obtained using data collected with the ATLAS and CMS experiments in proton-proton collisions at centre-of-mass energies of 7 TeV and 8 TeV. References to the latest results by the Tevatron experiments are also given. The data are compared with several predictions from perturbative QCD calculations up to approximate next-to-next-to-leading-order precision (approx. NNLO).
