Does the new version supersede the previous version?: Yes, the new version includes all known features of the previous versions but also provides the new features mentioned below.

Nature of problem:
A supersymmetric model is usually characterized by the particle content, the gauge sector and the superpotenial. It is a time consuming process to obtain all necessary information for phenomenological studies from these basic ingredients.

Solution method:
Non-supersymmetric models are supported by the new possibility to define not only chiral superfields but also component fields. The renormalization group equations (RGEs) for a non-supersymmetric models are calculated by using the generic formulae for a general quantum field theory.

Reasons for new version:
New features in the definition of models and a full support of non-supersymmetric models. New output for Vevacious.

Summary of revisions:
Support of non-supersymmetric models; calculation of renormalization group equations for a general gauge theory; link to Susyno for handling of non-SU(N) gauge groups; support of global symmetries; output of model files for Vevacious; support of aligned VEVs; calculation of gauge dependent parts of RGEs for VEVs in running of supersymmetric and non-supersymmetric models.

Only renormalizable terms in the Lagrangian are supported. No support of fields with spin 2 or 3/2.

Unusual features:
Calculation of non-supersymmetric RGEs includes effects of kinetic mixing as well as gauge dependence of running vacuum expectation values. SARAH is the first tool which can automatically create model files for Vevacious. Fully automatized derivation of all terms in the Lagrangian which are fixed by gauge invariance.

Running time:
Loading the Standard Model: 1.6s; calculation of all vertices: 11.8s; calculation of all RGEs: 130.2s ; output for Vevacious model files: 0.1s; output of model files in UFO format: 0.8s; output of model files for FeynArts: 0.1s; output of model files for CalcHep: 0.8s; output of model files for WHIZARD: 3.5s; writing of source code for SPheno: 34.5s. All times measured on Lenovo X220 with Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz.
