Go package for Lorentz vector

Word of caution

This repository is primarily to practice. The stucture is probably not optimal for a proper package structure, but this might evolve. For now, it is just to better undertand how to create/manipulate the go langage. The maths are mostly taken from TLorentzVector ROOT class.

Content

The lorentz vector object is a four-component object used in high energy physics, and is implemented as a 3D vector and a fourth component {r2.Vector, P4} object. The package relies then naturally on github.com/golang/geo/r3 package (3D vectors).

The repository is structured as follow:

• lv/lorentzvector.go: code of of the package lv (which should be in $GOPATH/src/<something> in order to be used in a go program)
• cmd/main.go: usage example of the lv package

To-do

• cross-check the definition of gamma2 since it is not gamma*gamma, change the variable name
• cross-check the v.Phi() value if this is in [0, 2pi] as in HEP convention
• compare values, boosted vectors, etc with other existing codes
