No b-jet and tau-jet is obtained using the delphe3.2.0 and test.tcl

[degos]

Hi,

I tested the test.tcl and Delphes3.2.0 again. I use the madgraph5 to generate 10000 gg > bb events (PT_b > 20 and drbb > 0.4). The Delphes_card.dat in madgraph5 is completelly with test.tcl, and then let the madgraph5 call Delphes3.2.0 to reconstruct the events. Although the large rates of b-tagging and tau-tagging are taken, I have no b-jet and tau-jet.

The fake rates of jet to electron, muon and photon are taken as 0. b-tagging and tau-tagging module are as follows:
###########
# b-tagging
###########

module BTagging BTagging {

set JetInputArray JetEnergyScale/jets

# (I try to add the "set PartonInputArray Delphes/partons", but no use.)

set BitNumber 0

add EfficiencyFormula {0} {0.001}

# efficiency formula for c-jets (misidentification rate)
add EfficiencyFormula {4} { (pt <= 15.0) * (0.000) +

(abs(eta) <= 1.2) * (pt > 15.0) * (0.20) + (abs(eta) > 1.2 && abs(eta) <= 2.5) * (pt > 15.0) * (0.10)

+ (abs(eta) > 2.5) * (0.000)}

# efficiency formula for b-jets
add EfficiencyFormula {5} { (pt <= 15.0) * (0.000) +

(abs(eta) <= 1.2) * (pt > 15.0) * (0.40) +

(abs(eta) > 1.2 && abs(eta) <= 2.5) * (pt > 15.0) * (0.40) + (abs(eta) > 2.5) * (0.000)}

}

module TauTagging TauTagging {

set ParticleInputArray Delphes/allParticles
set PartonInputArray Delphes/partons
set JetInputArray JetEnergyScale/jets

set DeltaR 0.5

set TauPTMin 1.0

set TauEtaMax 2.5

# add EfficiencyFormula {abs(PDG code)} {efficiency formula as a function of eta and pt}

# default efficiency formula (misidentification rate)
add EfficiencyFormula {0} {0.5}
# efficiency formula for tau-jets
add EfficiencyFormula {15} {0.4}

Hi,

given the final state you mentioned in ticket #725 I assumed you did not need b/tau jets. This said, I have attached a new version of the card called test_v2.tcl in #725. If you have further comments on this topic please post them in #725, I will close this ticket now.
