How to Extract Displaced Vertex

[haolin]

Hi,

I would like to know how to extract the information of displaced vertex associate with reconstructed objects like electron, muon, and jet

I saw a class variable "TRef Particle" and it seem to be some pointer to the candidate class where there is information of D0 and DZ, but I could not refer to this pointer since it always gives a null pointer.

Do does Delphes provide any method to extract the information of displaced vertex easily?

Thanks,
Haolin

The particle pointer you are reffering to gives you access to X,Y,Z or the production vertex, which seems to be what you want.
