Automatized generation of non-SUSY RGEs for a general gauge field theory


  • Florian LYONNET


In light of the conspicuous absence of SUSY in the energy range explored by the LHC in 2012, non-supersymmetric BSM scenarios are becoming more and more attractive. One key ingredient in exploring such BSM physics are the renormalization group equations (RGEs) that are essential for extrapolating the theory to higher energy scales. Although the 2-loop RGEs for a general quantum field theory are known since a long time, there is no easy-to-use tool that automatically generates them (for supersymmetric models, see the Mathematica package SARAH by F. Staub). In this talk, I will present a set of Python programs that generate the RGEs for an arbitrary model that is specified in terms of its gauge group and particle content. Then I will discuss its application to some simple BSM scenarios like the extension of the SM by vectorlike quarks and leptons. This is work in progress in collaboration with Ingo Schienbein, Florian Staub and Akin Wingerter.
