A library for working with four-vectors (or Lorentz vectors).
This library is mostly aimed at high energy physics applications, but should be general enough for usage in special relativity.
The library is intended to be usable for both space-time vectors and four-momenta. Therefore this library includes functions and methods with the common names for both usecases.
The design of this library is strongly inspired by the class
TLorentzVector from the C++ particle physics data analysis
framework ROOT. However it differs from `TLorentzVector in several
key aspects which are listed in the [Comparison with TLorentzVector]
section.
