The subtraction of thermal momentum components required when including recoil effects takes place in the analysis
of the events. For a detailed documentation of the procedure please refer to the
paper. An example
Rivet analysis can be found
How to run the analysis
Download and install Rivet (make sure you have a Rivet 2.x.y release). Set up the environment:
First the analysis has to be compiled as a pugin to Rivet.
rivet-buildplugin Rivet_JEWEL_BKGSUBTRACTION.so JEWEL_BKGSUBTRACTION.cc
Run JEWEL and store the hepmc events in a file, say test.hepmc. Then run the Rivet analysis:
rivet --pwd -a JEWEL_BKGSUBTRACTION -H out.yoda test.hepmc
The .yoda file contains the histograms in YODA format.
The analysis fills four histograms with the jet pT-spectrum, once un-subtracted and one for each subtraction method. To plot the histograms:
rivet-mkhtml --mc-errs out.yoda
This creates a directory plots containing a html page with the plots, which you can view by pointing
your favourite browser at plots/index.html
For further information on writing Rivet analyses, formating your plots etc. please refer to the Rivet documentation.
