Description

We provide analytic results for two-loop five-point scattering amplitudes in massless QCD in full colour.If you use the results distributed with this repository in your research work, please cite 2311.09870.There are two archives:twoloop.fivept.qcd.fullcolour.tar.gz: contains all the analytic results in Mathematica readable format together with a set of auxiliary files, useful to obtain complete results for all possible partonic channels. A README file with a detailed description of the repository is provided, as well as an examples folder.xings.pentagonfunctions.tar.gz: contains a set of files with all the necessary crossing identities for the pentagon functions. These files are named after the permutation they refer to, and we adopt the cycle notation. The files contained in this archive are needed to derive the complete set of results in various crossed channels.Some of the numerical results presented in the examples have been obtained using PentagonFunctions-cpp and PentagonMI (see 2009.07803). For numerical evaluation of the pentagon functions their installation is required.For a detailed description of the repository, we refer the interested user to the README file.From v1 to this v2: changes affect only the archive "twoloop.fivept.qcd.fullcolour.tar.gz". Differences with respect to v1:- fixed error in color matrix for the partonic process "0 - qb q g g g" [thanks to G. De Laurentis, H. Ita, M. Klinkert and V. Sotnikov for reporting]- extended example: now all partonic channels presented in Table II of 2311.09870 are included- added README also in "examples" folder
