| Summary: | 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 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 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. Also one- and two-loop corrections to tadpoles and self-energies can be obtained.
For numerical calculations SARAH can 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 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.
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 to
study all phenomenological aspects of a model. |
