Jet faking as leptons

[S. Niyogi]

Hello,

I got this card from a previous ticket which has a module for jet mis-identified as a lepton. There is module called Jet Fake. I want to know if the line

add EfficiencyFormula {11} { (eta <= 2.5) * (pt > 20.0) * (0.30)}

means the probability of a jet within |eta| <= 2.5 and pt > 20 will be mistagged as an electron is 30%, Is this correct ? Also, the PID for electron 11 is used, not for positron (i.e. -11). Does delphes

automatically understand that 11 is for both e- and e+ ?

Thanks for your help.

Regards,
Saurabh

There is an "abs" missing for eta. It should be:

add EfficiencyFormula? {11} { (abs(eta) <= 2.5) * (pt > 20.0) * (0.30)}

But, yes, it automatically understand electron and positron.
