Classical angular momentum in multi-body systems
This paper analyzes the concept of grand angular momentum, used in quantum studies of systems with multiple bodies, and applies it to classical physics problems. Using tree diagrams to represent different coordinate systems, the authors decompose the grand angular momentum into regular 3D angular momenta. This allows generalizing some 2-body results, and deriving an expression for the scattering angle in a general multi-body system.
