Eta cut on b-jets?

Asked by Billy Ford on 2019-06-10

Hi,

Just want to check something on cutting eta on b-jets. Firstly am I correct in thinking that the standard cut, using select ABSETA(b) < 2.5, is applied on the tagged b-jets (post reconstruction)? If so, is there a way to apply this cut on the hadrons/pseudojets before they are passed to reconstruction in fast jet in 'normal' mode?

Thanks,

Billy

Hi,

What you want cannot be done without hacking the code. I can point to you where exactly, if you want to try by yourself.

Cheers,

Benjamin

Hi Billy,

The code driving the run of fastjet is given here:
  /tools/SampleAnalyzer/Interfaces/fastjet/ClusterAlgoFastJet.cpp
