Description

Hello,
I would like to use Delphes with ideal detector, mainly to just get jets clustered with Fastjet from the Pythia output of the MadGraph5-Pythia-Delphes interface.
I tried to switch off modules not related with jet clustering, but I always get errors. Is there a simple way to achieve this? Or a sample delphes_card for ideal detector?

Thanks in advance.
Best regards,
Riccardo Torre

Hi Riccardo,

I guess by ideal you mean with infinite detector resolution, hence jets formed out of MC truth particles. In this case you already get what you want in the GenJet collection (either by running the CMS or ATLAS card). The GenJets are clustered from all stable particles from pythia except neutrinos, that are filtered out. If you want them back in, you can replace 

  set InputArray NeutrinoFilter/filteredParticles

by

set InputArray Delphes/stableParticles

in the MC truth jet finder section of the card.

Hope this helps,
Michele
