#884: Delphes card in Madgraph:

[Najimuddin Khan]

Hi,
Thank u so much for the reply. I add the part in my delphes_card. Although I need to clarify some of my doubts.
In the calorimeter section, one has the following commands :

add EnergyFraction {12} {0.0 0.0}
add EnergyFraction {13} {0.0 0.0}
add EnergyFraction {14} {0.0 0.0}
add EnergyFraction {16} {0.0 0.0}
add EnergyFraction {1000022} {0.0 0.0}
add EnergyFraction {1000023} {0.0 0.0}
add EnergyFraction {1000025} {0.0 0.0}
add EnergyFraction {1000035} {0.0 0.0}
add EnergyFraction {1000045} {0.0 0.0}

for pdg = 12 ,14, 16 , 1000022 it is understood that since they are the undetected ones they donot deposit energy in electron as well as hadron calorimeter. but what about other neutralinos ? how are they distinguished from the LSP in delphes_card? or in other words, is it sufficient just to add the line "add EnergyFraction {x} {0.0 0.0}" in the card to instruct it to be counted as "invisible" or some other changes are required?

It would be very helpful if you can give some insight.

Yes, it should be sufficient.
Sometimes if the particle is not known it will be counted as invisible anyway, see #753.
