Verbesserung und Weiterentwicklung von "DsixTools: The Standard Model Effective Field Theory Toolkit"
Zusammenfassung der Projektergebnisse
DsixTools was created in 2017 with the objective of automatizing analyses in the Standard Model EFT with Mathematica. Since then, new theory results have appeared that called to be included in the package, beyond those improvements that were left out from the first version of DsixTools due to a lack of organizational infrastructure. The DFG Scientific Network provided such infrastructure and made it possible to develop the second version DsixTools 2.0, available at https://dsixtools.github.io This version is drastically different from the first one in scope and in spirit. Some of the key improvements it contains are: ● The full Low Energy EFT (LEFT) below the EW scale has been implemented, with complete one-loop running. ● The full one-loop matching between the SMEFT and the LEFT. ● SM beta functions up to five loops, and QCD beta function and mass anomalous dimensions in the LEFT up to four loops. ● A third method for RG evolution both in the SMEFT and the LEFT has been implemented, which is as precise as the exact solution of the RGEs but much faster. ● A full reference guide for the SMEFT and the LEFT is provided within the package, which works also as a repository for the EFT practitioner. ● A complete Mathematica documentation system is included. The Scientific Network had also a few other side-outputs, such as: The independent confirmation of the tree-level SMEFT-LEFT matching conditions in two different ways (functional and diagrammatic approaches); the organization of the SMEFT 2020 Physics school. Although the Scientific Network had to be stopped before its intended finalization date, we believe the main objectives have been achieved. We are confident that the final product, DsixTools 2.0, will be used extensively by the hep-ph community, leading to many phenomenological papers of great interest.
