Description
Hi!
I have already run Delphes (3.0.9) for a large number of events, but would now like to change the b-tagging efficiency. Does Delphes include a way to access the truth information for jets or a b-jet flag that I could use? I tried looping over the Jet.Constituents array, but it contained only muons (is this normal or should it contain a full record of constituents?).
I am using the Snowmass delphes cards.
I can modify the card to include a perfectly efficient b-tagger but I am hoping that there is a way to access this information already included.
Thanks,
Alex

Hi Alex,
It's possible to restore jet flavor using the information from the GenParticle branch.
If I remember well, the Snowmass card keeps b-quarks. So, you can match jets with b-quarks and then apply new b-tagging efficiency.
Currently, there is no b-jet flag. We can add it. Thanks for the suggestion.
Regards,
Pavel
