TLorentzVector units

Hi all,
as you can imagine, I am working with the TLorentzVector class and plot the pT spectrum of some daughter particles and want to cross check them with my calculations.
What Units does the pT spectrum and the Energy spectrum have?
My suggestion is for pT GeV and Energy MeV but since I am not sure I ask.

Hi @kohle; I guess @moneta knows the answer.


TLorentzVector has no “built-in” units.
The user must use “consistent” values for all quantities in a particular four-vector.
