# FlexibleSUSY

FlexibleSUSY is a Mathematica and C++ framework to create fast and modular spectrum generators for supersymmetric and non-supersymmetric models. It is based on SARAH and uses some components from SOFTSUSY.

## News

• 2017-10-20: FlexibleSUSY 2.0.1 has been released. New feature: For each model the TeX file <model>_references.tex is generated, which contains \cite{} commands with references to be cited when the model is used. Bug fixes: Include missing 2-loop gluino contribution to yt in the split-MSSM (Thanks to Pietro Slavich). configure no longer hangs when Mathematica fails to find a valid license (Thanks to Anders Kvellestad).
• 2017-10-10: FlexibleSUSY 2.0.0 has been released. New features: Prediction of W mass (FlexibleMW), anomalous magnetic moment of the muon (FlexibleAMU), semi-analytic solver (FlexibleSAS), electric dipole moments (FlexibleEDM), improved FlexibleEFTHiggs, complete 2-loop threshold corrections O(αstb) + (αtb)2 + ατ2) for HSSUSY [arxiv:1703.08166], 2-loop SQCD threshold corrections in the MSSM, 3-loop threshold corrections in the Standard Model, 3-loop contributions O(αs2tb)) to the light CP-even Higgs mass in the MSSM (requires Himalaya) and many more. All new features are documented in [arxiv:1710.03760].
• 2017-09-05: FlexibleSUSY 1.7.5 has been released. This version fixes two vertices in the muon decay, a wrong coefficient in the complex dilogarithm and allows to pass matrix-valued parameters to the Set[] functions of FlexibleSUSY's Mathematica interface.
• 2017-08-22: FlexibleSUSY 1.7.4+Himalaya has been released [1708.05720]. This is a standalone version of FlexibleSUSY 1.7.4, which contains three pre-generated MSSM spectrum generators to calculate the lightest CP-even Higgs pole mass in the MSSM at the 3-loop level using the Himalaya library.
Note: Himalaya must be downloaded separately. See the installation description or the README file in the FlexibleSUSY+Himalaya tarball for further details.
• 2017-04-12: FlexibleSUSY 1.7.4 has been released. This version fixes a bug in the 2-loop beta function of the SM vacuum expectation value as well as a compatibility bug with SARAH 4.11.0.
• 2017-02-27: FlexibleSUSY 1.7.3 has been released. This version fixes a bug in the CMSSMCPV model file and implements missing limits of the threshold correction functions for HSSUSY [arXiv:1407.4081].
• 2016-12-15: FlexibleSUSY 1.7.2 has been released. This version fixes a bug in the 2-loop and 3-loop SM-QCD contributions to the top pole mass and top Yukawa coupling in non-SUSY models.
• 2016-10-15: FlexibleSUSY 1.7.1 has been released. This version includes GM2Calc 1.3.0 and simplifies the configuration options for FlexibleEFTHiggs.
• 2016-09-19: FlexibleSUSY 1.7.0 has been released. This version includes FlexibleEFTHiggs and a Mathematica interface for the spectrum generators generated with FlexibleSUSY.
• 2016-09-03: Standalone FlexibleEFTHiggs spectrum generators for the MSSM, NMSSM, E6SSM and NMSSM have been released.
