Description
Dear expert,
I have a question related to the Jet object in the Delphes tree.
I would like to track back the origin of this jet to the parton level, do I have any way to get this information in the Jet object?
I see there are two variables likely to give the information:
Constituents references to constituents
Particles references to generated particles
but I don't on earth what are these two thing refer to.
Sincerely,
Haolin

See TracTickets
for help on using tickets.
You can have a look at Example3.C for that. For GenJets only the !Particle collection matters. For reconstructed jets using particle flow you should look at towers and tracks.
