pgs - card

Asked by Safinaz

Dear MadGraph team,

I'd like to know how to determine pgs detector simulator run variables through the pgs_cards.dat files
in the Madgraph cards folder, specifically the jet clustering algorithm , the radius cone parameter and
the efficiencies implemented for particle tagging, jet tagging or momentum ..

I found that there are many pgs cards like : pgs_card.dat , pgs_card_LHC.dat and pgs_card_CMS.dat, I used the last
card since I work on CMS. Now for the jet clustering algorithm , I found

cone ! jet finding algorithm (cone or ktjet) --> I think I can change to ktjet instead of cone algorithm
0.5 ! calorimeter kt cluster finder cone size (delta R) --> I think that's the cone radius of the partons jet,
so is (delta R) here different form DeltaR distance in the run_card defined as distance between jets.

What about the efficiencies implemented for the detector simulator, could they defined ..

Thanks,
Safinaz

Dear Safinaz,

Please contact the delphes team for all questions related to Delphes. We just provide an interface to their tools, and
we have actually no idea on how this code works.

This being said, the card that you mention (and the part that you paste) are the cards for Delphes2.
We still keep them for retro-compatibility issue. But now the default version of Delphes is Delphes3 (and this is the one install via the command “install Delphes”).
The input card for Delphes2 are actually not compatible with those of Delphes3.

In Delphes3, you have actually much more freedom to play with parameter/efficiency/…

Cheers,

Olivier
