This is a tutorial explaining how to generate HERWIG++ signal plus pile up events. You need a Linux computer (this was tested on SL5.9) with installed ROOT. Also, certain libraries require “boost” library:

yum install boost-devel

Then get this tar file which includes HERWIG++, ThePEG, Delphes 3.08, Pythia8, HEPMC. package.tgz

export PATH=.:$PATH
wget http://mc.hep.anl.gov/asc/snowmass2013/delphes36/packages/package.tgz
tar -zvxf package.tgz
cd package_snowmass13
build.sh # if this is SL5.9, do not need to run this script!

The build script attempts to detect your environments and the installs HERWIG++, ThePEG, Delphes 3.08, HEPMC (not in the same order) If some luck, installation can be successful.

To generate pileup (example):

cd  herwigpp/run_pileup_ttbar_highPT
A_RUN_pileup.sh*

To generate signal:

cd  herwigpp/run_pileup_ttbar_highPT
A_RUN_signal.sh

Please examine it. If you need to change the signal events, look at the HERWIG++ “LHC_signal.in” card, where you can set needed process.
