A package to allow the Invisible Higgs samples to decay with Pythia.

Assuming Pythia can be run with the already exisiting object file: pythia-6.4.28.o If not make sure your gfortran location is in your path:

$ which gfortran $ gf=$(which gfortran) $ export PATH=$gf:$PATH

or put in your bash profile for convenience

then:

$ gfortran -c pythia-6.4.28.f

Start by running the script:

  ./decayLHEs

This should compile the analysis code main81.f with Pythia.

Note, this needs to be run each time the code changes.

Then run the executable:

 ./decay

This allows the hard process to decay through Pythia.

NB: main81.f is a generic code that reads an LHE, made either externally or with Pythia, and allows analyses of the process contained NB: LHEinfo.sh is a script that returns the number of events stored per lhe. It requires the LHE as an argument. NB: The Higgs decay H-> Z Z is known to Pythia with the decay mode number: 225 The Z decay Z -> v v is known to Pythia with the decay mode number: 183/ 185/ 187 for electrons, muon & tau neutrinos

The PDG ID for the Higgs= 25
      	    	 Z boson= 23
	      e neutrino= 12
             mu neutrino= 14
            tau neutrino= 16
