Description
I am interested in the impact parameter smearing functionality of Delphes (as used in the TrackCountingBTagging module and also the TrackSmearing module). However, I tried to access ErrorD0 using the default CMS card and found that it was not being calculated. The documentation referred to on the Delphes website (btagging_v2.pdf) also did not explain how exactly to obtain ErrorD0. It appears that ErrorD0 is being calculated in TrackSmearing.cc, but to use this I need a resolution function which is not provided.
Any further information on this would be most appreciated. Also, if all that is needed is a resolution function for TrackSmearing.cc, then would it be possible to provide the resolution function appropriate for CMS (eg that which went into the plots in btagging_v2.pdf)?
Many thanks,
David
Hi David,
I also started looking into these modules recently and found that some of them were out of date. I just submitted a PR to Delphes with updates: https://github.com/delphes/delphes/pull/44. Take a look and let me know if things make sense.
