The newest version of SARAH now provides the possibility to create model files in the UFO format which is supported by MadGraph 5, MadAnalysis 5, GoSam, and soon by Herwig++. This allows SARAH to create model files for FeynArts/FormCalc, CalcHep/CompHep and WHIZARD/O'Mega. SARAH is a Mathematica package optimized for the fast, efficient and precise study of supersymmetric models beyond the MSSM: a new model can be defined in a short form and all vertices are derived. SARAH 3.2: Dirac gauginos, UFO output, and more In particular, the interface to SPheno allows a precise prediction of the Higgs mass in a given model comparable to MSSM precision by incorporating the important two-loop corrections. For numerical calculations SARAH can be interfaced to other tools to get the mass spectrum, to check flavour or dark matter constraints, and to test the vacuum stability, or to perform collider studies. Also one- and two-loop corrections to tadpoles and self-energies can be obtained. All of these models can be implemented in a compact form in SARAH and are easy to use: SARAH extracts all analytical properties of the given model like two-loop renormalization group equations, tadpole equations, mass matrices and vertices. In general, SARAH can handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses. I give an overview about the features the Mathematica package SARAH provides to study new models. Finally, the main commands to generate model files and output for other tools are summarised.Įxploring new models in all detail with SARAH In the second part, masses, vertices and renormalisation group equations are calculated with SARAH. First, it is shown how an existing model file can be changed to implement a new model in SARAH. I give in this brief tutorial a short practical introduction to the Mathematica package SARAH.
