Namespaces
==========

This page provides documentation for key namespaces in AnalysisG.

Physics Namespace
-----------------

The ``physics_`` namespace contains functions for common high energy physics calculations
including momentum, mass, and angular calculations.

For complete function signatures and documentation, see the Doxygen-generated HTML
documentation.

Key Functions
~~~~~~~~~~~~~

The physics namespace includes functions for:

* **Momentum calculations**: P2(), P() for momentum squared and magnitude
* **Velocity**: Beta2(), Beta() for particle velocity
* **Mass**: M2(), M(), Mt2(), Mt() for invariant and transverse mass
* **Angles**: Theta() for polar angle, DeltaR() for angular separation

Other Namespaces
----------------

The following namespaces provide additional functionality:

* **transform**: Coordinate system transformations
* **operators**: Tensor aggregation and reduction operations  
* **graph**: Graph construction utilities
* **nusol**: Neutrino solution algorithms
* **utils**: Utility functions and helpers

For complete documentation of all namespaces, functions, and classes, see the
full Doxygen HTML documentation generated by running ``doxygen Doxyfile``.
