A program for the calculation of the decay widths and the branching ratios
of the supersymmetric particles in the MSSM.
A program package has been created, called SUSY-HIT.
It calculates the MSSM Higgs bosons and SUSY particle decays including
higher orders, and consists of the Fortran77 codes HDECAY and SDECAY. The
spectrum calculator SuSpect
has been linked by default, can be replaced,
however, by any spectrum program which uses the SLHA output format. The url
address of the program package is:
is the official reference to be used for the program.
The Fortran code SDECAY deals with the decays of SUSY particles in the
framework of the MSSM and includes the most important higher order effects:
Up to the user's choice, it can read in spectrum files in the
SUSY Les Houches Accord (SLHA) format,
hep-ph/0311123,
or it uses the RGE program SuSpect for the
calculation of the mass
spectrum and the soft SUSY-breaking parameters. It then evaluates the
various couplings of the SUSY particles and MSSM Higgs bosons.
It calculates thedecay widths and the branching
ratios ofall the two-body decay modes, including the QCD corrections to the
processes involving squarks and gluinos and the
dominant electroweak effects to all processes.
It calculates the loop induced two-body decay channels, as
well as all
the possibly important higher order decay modes:
the three-body decays of charginos, neutralinos, gluinos, top
squarks and sbottom squarks and
the four-body decays of the top squark.
The program also calculates the decay widths and branching ratios of
the heavy top quark and will include the one-loop
SUSY-QCD radiative corrections.
Up to the user's choice the output file can be given
in the SLHA format.
Here, we provide the source code and manual, updated
information on changes, bugs, etc..
Information on SDECAY:
Short explanations of the code are given in the file
sdecay.readme.

Updated!
Modifs/corrected bugs are indicated explicitly

Downloading the files needed for SDECAY:
sdecay.in : the input file of the
program (last modif: March 4, 2005).
sdecay.f: the main program SDECAY
(ver 1.3, last modif: Oct 25, 2007).
SuSpect2.uu: all the needed SuSpect files
(ver 2.34/Oct 25, 2007).
Makefile for the compilation (last modif: March 4,
2005).
Example for an output file:
The input files sdecay.in and
suspect2.in
(snowmass point SPS1a) provide the output files
sdecay.out a la
Les Houches Accord (last modif: Oct 25,
2007)
and in a simple form
(last modif: Oct 25, 2007).
