How to create a MCDecayTreeTuple from the .xgen file for Z(->mu mu) + gamma
Now I can produce a Gauss-42112100-10000ev-20230404.xgen for # Descriptor: pp -> (Z0gamma -> mu+ mu- gamma) ...
.
But I couldn't get a root file using the following command.
lb-run -c best DaVinci/v45r4 gaudirun.py MCZgammatuple.py
My option file is put here. MCZgammatuple.py The Feynman diagram is put here.
