Top Pair Differential Distribution of Top pT at 8 TeV NLO vs NNLO Summary

Figure	Description
Pair production differential cross sections
	Full phase-space normalised differential ttbar cross-section as a function of the transverse momentum of the top quark. The CMS and ATLAS results are compared to the NLO and NNLO calculations from arXiv:1606.03350. The values for the top-quark mass (mtop), the renormalisation (muR) and factorisation (muF) scales, and the choice of the PDF set used in each calculation are provided. The variable mT is defined as the square root of the sum of the squares of top-quark mass and the transverse momentum of the top quark. Both the CMS and ATLAS measurements are performed assuming a top-quark mass value of 172.5 GeV. The shaded bands show the total uncertainty on the data measurements in each bin. The lower panel shows the ratio of the data measurements and the NLO calculation to the NNLO calculation. PNG PDF November 2017
