Exploring New Models in All Detail with SARAH

Abstract EN

I give an overview about the features the Mathematica package SARAH provides to study new models.

In general, SARAH can handle a wide range of models beyond the MSSMcoming with additional chiral superfields, extra gauge groups, or distinctive features likeDirac gaugino masses.

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 liketwo-loop renormalization group equations, tadpole equations, mass matrices, andvertices.

Also one- and two-loop corrections to tadpoles and self-energies can be obtained.

For numerical calculations SARAH can be interfacedwith other tools to get the mass spectrum, to check flavour or dark matter constraints, and to test the vacuumstability or to perform collider studies.

In particular, the interface to SPheno allows aprecise prediction of the Higgs mass in a given model comparable to MSSM precisionby incorporating the important two-loop corrections.

I show in great detail with the example of the B-L-SSM how SARAH together with SPheno, HiggsBounds/HiggsSignals, FlavorKit, Vevacious, CalcHep, MicrOmegas, WHIZARD, and MadGraph can be used tostudy all phenomenological aspects of a model.
