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.

2-dim LHC 8 TeV distributions for CMS binning arXiv:1703.01630. Top quark mass: mt=173.3 GeV. Computed are the following pairs of observables: {PTavt, Yavt}, {Mtt, Yavt}, {Mtt, Ytt}, {Mtt, detatt}, {Mtt, PTtt}. For details and definitions please see the README file inside the tarball.

Included are both the fastNLO tables and .dat files computed with specific PDF sets.

Publication is to appear. Meanwhile, if you use these results please refer to them as “Czakon, Mitov, Papanastasiou (2018), to appear.”
