How to Find the Number of Muons;

Description

I am trying to find the number of Muons generated in the Muons Branch. When I open the Delphes Analysis tree in my TBrowser in ROOT, I can only find the Muon.PT, Muon.Phi, Muon.Eta branches (and others). However, there is no mass or energy branches so I am not able to calculate invariant mass or create TLorentzVectors easily. Is there a way to have mass branch available in the delphes tree? Also, I find in some tutorials that there is also the number of Muons generated in the Muon Branch available as well (called nMuon). However, I do not see an nMuon Variable that shows the number of muons. Is there a way to find the number of Muons? Is it possible to add it to my Delphes Analysis tree either directly (through the delphes card) or through ROOT? How would I do that?
