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… 
Precision Calculations in Supersymmetric Models using Phenomenological Tools
We present a Higgs mass calculation at two-loop level based on the effective potential approach, which has been made available in the public computer codes SARAH and SPheno. The approach is based on
Precise determination of the Higgs mass in supersymmetric models with vectorlike tops and the impact on naturalness in minimal GMSB
A bstractWe present a precise analysis of the Higgs mass corrections stemming from vectorlike top partners in supersymmetric models. We reduce the theoretical uncertainty compared to previous studies
A new tool for the study of the CP-violating NMSSM
A bstractSupersymmetric extensions of the Standard Model open up the possibility for new types of CP-violation. We consider the case of the Next-to-Minimal Supersymmetric Standard Model where, beyond
Matching renormalisable couplings: simple schemes and a plot
We discuss different choices that can be made when matching a general high-energy theory onto a general renormalisable effective field theory at one loop, with particular attention to the quartic
Precision tools and models to narrow in on the 750 GeV diphoton resonance
The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered a significant amount of attention. Since the simplest extensions of the standard model cannot accommodate the observation,
High scale impact in alignment and decoupling in two-Higgs-doublet models
The two-Higgs-doublet model (2HDM) provides an excellent benchmark to study physics beyond the Standard Model (SM). In this work, we discuss how the behavior of the model at high-energy scales causes
Revisiting fine-tuning in the MSSM
A bstractWe evaluate the amount of fine-tuning in constrained versions of the minimal supersymmetric standard model (MSSM), with different boundary conditions at the GUT scale. Specifically we study
Supersymmetric and non-supersymmetric models without catastrophic Goldstone bosons
TLDR
Some first steps to exploring where the habit of using tree-level mass relations in non-supersymmetric models breaks down are taken, and it is shown that the loop corrections usually become very large well before naive perturbativity bounds are reached.
