Description
the b-tagging efficiency of the default delphes card for atlas detector should be 65-70%, however when I check this efficiency with a small process, it is only about 30%. Does this mean that the default efficiency is not 65-70%? I am looking for your kind reply

Hello,
Since the b-tagging depends on the algorithm used and on the efficiency vs purity chosen in the analysis. We provide a default value, but it is recommended to adapt the b-tagging.
This can be done in the tcl ATLAS card: examples/delphes_card_ATLAS.tcl
after the lines :

# b-tagging

I hope that this will help you!
Cheers,
Alexandre
