Description

Dear Delphes authors,

I am looking to extract the information of energy deposits in the calorimeters. How do I go about it?

Regards,

Juhi

You can start by looking at this page:

https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/RootTreeDescription,
the relevant class is Tower.
In order to access towers you have to store them in the output. If you are using the default CMS or ATLAS cards it should be already in there.

Thanks for the reply.

In the default cards, there are three inputs to the Tower in the line 1,3,4. Doesn't Calorimeter/towers already include the photons and neutral hadrons? Why are the EFlowPhoton and EFlowNeutralHadron being added separately?

  1. add Branch Calorimeter/towers Tower Tower
  1. add Branch Calorimeter/eflowTracks EFlowTrack Track
  2. add Branch Calorimeter/eflowPhotons EFlowPhoton Tower
  3. add Branch Calorimeter/eflowNeutralHadrons EFlowNeutralHadron Tower

Regards,

Juhi
