Pileup btagging

Description

Dear Delphes team,

I'm trying to use the Pile Up functionality in Delphes 3.0.9. I've created a MinimumBias file with Pythia 8. My problem is that everything go well except for the fact that no btagged jet are present in the delphes tree, when using a card without pileup gives a completely different situation. Is there something physical I cannot understand or it's a Delphes problem?

Thank you

Giancarlo Panizzo

Hi Giancarlo,

are you using the default delphes_card_CMS_PileUp.tcl?
If yes, you should change the following line in the card at B-tagging/Tau tagging modules level (lines 569,603):

set JetInputArray FastJetFinder/jets

into

set JetInputArray JetPileUpSubtractor/jets

Does this solve your issue? In the next release this typo will be fixed. Sorry for the inconvenience.

Michele

I'm using an home made card generated merging CMS_PileUp and ATLAS cards, and yes, this solves the problem!
Thank a lot
