BTagging
determines origin of jet, applies b-tagging efficiency (miss identification rate) formulas and sets b-tagging flags
- input:
- PartonInputArray
- JetInputArray
- output:
- OutputArray
- parameters:
- DeltaR
- PartonPTMin
- PartonEtaMax
- EfficiencyFormula - efficiency (miss identification rate) specified for a PDG code as a function of transverse momentum and pseudo-rapidity
- BitNumber (default 0)
Starting from version 3.0.7 it is possible to test several (up to 32) b-tagging working points for every jet. The BTag variable in the Jet class can store up to 32 bits. If the user specifies BitNumber = 0 in the BTagging module, that particular bit will be stored in the first position. If BitNumber = 1, it will be in the second position, etc ...
In order to check whether a jet has passed the b-tagging criterium defined by the BitNumber = i, just do:
