Simple scripts to check:
- matrix element process
- gen level Higgs decay
To run (assuming a root file in local with nanoaod information, "nanoStep_231.root"):
root -l printLHEDecay.C\(\"nanoStep_231.root\",20\)
root -l printGenDecay.C\(\"nanoStep_231.root\",20\)
"20" here is the number of events to check
