Exploring New Models in All Detail withSARAH

Abstract

I give an overview about the features theMathematicapackageSARAHprovides to study new models. In general,SARAHcan handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses. All of these models can be implemented in a compact form inSARAHand are easy to use:SARAHextracts all analytical properties of the given model like two-loop renormalization group equations, tadpole equations, mass matrices, and vertices. Also one- and two-loop corrections to tadpoles and self-energies can be obtained. For numerical calculationsSARAHcan be interfaced with 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. In particular, the interface toSPhenoallows a precise prediction of the Higgs mass in a given model comparable to MSSM precision by incorporating the important two-loop corrections. I show in great detail with the example of theB-L-SSM howSARAHtogether withSPheno,HiggsBounds/HiggsSignals,FlavorKit,Vevacious,CalcHep,MicrOmegas,WHIZARD, andMadGraphcan be used to study all phenomenological aspects of a model.
