# 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.

## Current version

The latest release of FlexibleSUSY is 1.7.4 (released 12 April 2017).

The latest release of FlexibleSUSY+Himalaya is 1.7.4 (released 22 August 2017).

## News

• 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.
