We present the program package SUSY-HIT for the computation of supersymmetric particle decays within the framework of the Minimal Supersymmetric extension of the Standard Model. The code is based on two existing programs HDECAY and SDECAY for the calculation of the decay widths and branching ratios of, respectively, the MSSM Higgs bosons and the SUSY particles, and calls a program for the calculation of the SUSY particle spectrum such as SuSpect. Including all important higher order effects, the package allows the consistent calculation of the MSSM particle spectrum and decays with the presently highest level of precision.

Dark Matter through the Higgs portal (2019, methodology): “For this purpose, we have used the program HDECAY [204–206] which calculates the partial widths and the branching ratios of all Higgs decays (in the SM but also in some of its extensions like the 2HDM and the MSSM as will be seen later in this review) including all relevant higher order effects.”
Fully covering the MSSM Higgs sector at the LHC (2015, methodology): “At high tan β values, say tan β >∼ 10, the decay pattern of the heavier neutral H/A bosons is extremely simple [10, 82, 83] as a result of the strong enhancement of the couplings”
