FastNLO tables for top-pair production

This page contains FastNLO tables with top-quark-pair differential distributions in NNLO QCD for LHC. For details please see the publication: Czakon, Heymes, Mitov, arXiv:1704.08551.

The fastNLO toolkit, as well as instructions about how to convolute tables with pdf sets, can be obtained from the fastNLO website: http://fastnlo.hepforge.org. All tarballs below contain the tables as well as README files with further details and an example of how to use the tables.
