Abstract
A bstract : FlexibleSUSY is a framework for an automated calculation of observables in user-defined models of a Beyond the Standard Model (BSM) physics, starting from the model’s field content and its Lagrangian. Among a plethora of observables it is capable of calculating are the high precision predictions for Higgs bosons decay widths. Building on these previous developments we present here an interface between FlexibleSUSY and HiggsTools/Lilith. Combined with other FlexibleSUSY capabilities this extension provides a fully automatized tool chain leading directly from a user-defined BSM model to the state-of-the-art validation of the global agreement of a BSM Higgs sector with experimental measurements. We demonstrate this extension on a handful of phenomenologically relevant examples: a CP-conserving version of the Type-II Two Higgs Doublet Model, the CP-violating Next-to-Minimal Supersymmetric Standard Model and the Minimal R-symmetric Supersymmetric Standard Model. These examples show the power of FlexibleSUSY when applied to supersymmetric and non-supersymmetric models, both with and without CP-violation, and illustrate the handling of invisible and undetected decay widths.
