I discuss and compare several approaches to higher-order calculations of top quark production. I study the relative effectiveness of the approaches in approximating the exact NNLO results for the top-pair total cross section and highlight the theoretical and numerical differences between them. I show that the results from my soft-gluon resummation method are nearly identical to the exact NNLO cross section at all LHC and Tevatron energies. This agreement has important consequences for the validity of existing approximate NNLO differential distributions, for further refinements of the predictions, and for applications to other processes such as single-top production. I also compare approximate NNLO top quark transverse momentum and rapidity distributions with recent LHC measurements.

Original abstract

I discuss and compare several approaches to higher-order calculations of top quark production.

This agreement has important consequences for the validity of existing approximate NNLO differential distributions, for further refinements of the predictions, and for applications to other processes such as single-top production.

The validity and robustness of our fixed-order approach has been amply confirmed by its success in predicting the exact results at NNLO for $tt̅$ production as well as postdicting the NLO results for $tt̅$ and single-top production as well as other processes, as has already been discussed plenty of times before (see e.g. Refs. [ref] ).

The downside of this approach, however, is that the absolute size of the cross section might be difficult to determine due to QCD corrections, etc.[Theoretical calculations of the cross section for $tt̅$ pair production can be found in Ref. [ref] .
