Dear Root users,
Within root’s own Pythia tutorial, I am using the command ‘part->Vx();’ and ‘part->Vy()’ to get the x and y of the production vertices of particles within the TParticle class. I was wondering if anyone knows what the units are of the numbers being returned by this command. In general: what are the units of distance which are mostly being used within particle physics?
Best regards,
Loek
