Implement b-tag with external fastjet and write to root file.

[andrea.diluca]

I generated a HEPMC file using Pythia8. I would like to run Delphes with external fastjet. I saw the available examples to do that.
Do you have any suggestion on how to implement b-tagging on the reconstructed jet and how to write everything to root file(as it happens when running Delphes using internal fastjet)?
Thank you.

Hi,

I am not sure I understand exactly what you want to do.
You want to implement a proper b-tagging algorithm (using the jet constituents and displacement and so on?)
or something parameterised using the b-parton information as done in the b-tagging module inside Delphes?

Thanks for your reply.
Something parameterized as done by the b-tagging module inside Delphes could be enough.
