Description

Dear Delphes Experts,

Is it possible to get the impact parameter of charged pions produced from tau decay using any of the Delphes branch?

Assuming the primary vertex at (0,0,0), the information of secondary vertex position, I think, would give me the tau decay length vector and then it is possible to derive the impact parameter. Can you please suggest a way to get either of the above two (or both)? This would be really helpful.

Thanks and regards
Abhaya
