LorentzVectorHEP

Provides two types (and the conversion between the two):

• LorentzVector (energy, px, py, pz) (from LorentzVectors.jl)
• LorentzVectorCyl (pt, eta, phi, mass)

and these functions for both of them:

px, py, pz, energy, pt, eta, phi, mass

as well as these utility functions:

deltar, deltaeta, mt, mt2
