The generation of the source code for SPheno is started via
The different options are:
ReadLists->Truecan be used if all vertices and RGEs have already been calculated for the model and the former results should be used to save time.
InputFile. The name of the SPheno input file. If not defined,
StandardCompiler->Compile. The compiler which should be set as standard in the created Makefile. Default is gfortran.
The generated source code is located in
/Directory of SARAH/Output/$MODEL/$EIGENSTATES/SPheno/
These files can be compiled together with SPheno version 3.3.0 or later. SPheno is also available at HepForge:
The necessary steps to compile the new files are
tar -xf SPheno-3.3.0.tar.gz cd SPheno-3.3.0 mkdir $MODEL cp -r $PATH/SARAH-X.Y.Z/Output/MODEL/EWSB/SPheno/* MODEL make Model=$MODEL
This creates a new binary
bin/SPheno$MODEL which reads all input parameters from an external file. SARAH writes templates for these input file which can be used after filling it with numbers as
The output is written to
and contains all running parameters at the renormalization scale, the loop corrected mass spectrum, two and three-body decays as well as a prediction of precision and flavour observables.
