Different jet containers in same output file

I was wondering if it is possible to have two different set of jets in the output file. I am producing delphes output using antikt 0.4 jets and I would like to test my analysis using DR = 0.6. I would like to know if I can define a new container to be written in a new branch, for example, that contains these jets but still be able to access the 0.4 jets when reading the root file.

Hi Juanpe,

It's possible to have any number of jet branches in the output file.

In the example configuration files (delphes_card_ATLAS.tcl and delphes_card_CMS.tcl), the are already two jet branches defined: GenJet and Jet.

Here is how we added the GenJet branch:

  • copied module FastJetFinder with all its parameters and renamed it to GenJetFinder
  • added the GenJetFinder module to ExecutionPath
  • defined new branch in the TreeWriter module:
    add Branch GenJetFinder/jets GenJet Jet
