Soft gluons and top quark pair production
October 02, 2018
In this talk we summarize two recent efforts towards improving the theoretical predictions for the differential cross sections in top quark pair production. Both are related to the effect of soft gluons. The first result is the analytic calculation of the NNLO massive soft function which is an important ingredient in the resummation of threshold logarithms. The second is the matched NNLO+NNLL$'$ predictions which combine state-of-the-art NNLO QCD calculations with double resummation at NNLL$'$ accuracy of threshold logarithms arising from soft gluon emissions and of small mass logarithms.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
