Customized generationEstimated reading time: 2 minutes
Different analyese or different purpose could need some special event samples. Here a brief introduction of how to customize WHIZARD generation is provided.
Generate samples at different energy points
The first example is generate Higgs signal and standard model background process at different energy points.
The mkproc.sh script is used to make the steering files for all the processes defined in the input process(prc) file. Four parameters have to be send to mkproc.sh:
The pattern mkproc.sh works with:
-pmake all the SM backgrounds
-hmake the Higgs processes
-amake di-photon backgrounds
The prc file in which the required processes defined there are several well defined prc files in the directory:
2fermions.prcfor the 2 fermions SM backgrounds,
4fermions.prcfor the 4 fermions SM backgrounds,
6fermions.prcfor the 6 fermions SM backgrounds, including the t-tbar processes, specific to 350GeV,
higgs.prcfor the higgs production, classified according to the decay products of higgs,
gamma.prcfor the di-photon backgrounds, needs tuning.
The center of mass energy. Be aware that the 6fermions.prc is programed only under 350GeV case.
The directory where you want the samples located
The gramma is “
source mkproc.sh -pattern XXX.prc cms path”. After it completed, all the steering files will be created under the current location, and classified according to the processes defined in the prc file. The samples will be generated under the location specified by the parameter path.
source mkproc.sh -h higgs.prc Ecms path_for_generated_results
- source mkproc.sh -p 2fermions.prc Ecms path_for_generated_results
- source mkproc.sh -p 4fermions.prc Ecms path_for_generated_results
- source mkproc.sh -p 6fermions.prc Ecms path_for_generated_results
For the users who want to generate samples with specific models, first the model name in the prc should be changed to the new one, and the model file has to be installed at
all the necessary files can be find at /cefs/data/stdhep/generator
Generate exclusive Higgs signal process
After successful excecution of the “source mkproc.sh -h higgs.prc Ecms path_for_generated_results”, a directory will be created automaticlly at current location, named higgs. All combinations of $Z$ and $H$ decay modes can be found in this directory. It looks like
