The angular momentum controversy: What's it all about and does it matter?
by E. Leader, C. Lorce
Publisher: arXiv 2013
Number of pages: 96
The general question, crucial to an understanding of the internal structure of the nucleon, of how to split the total angular momentum of a photon or gluon into spin and orbital contributions is one of the most important and interesting challenges faced by gauge theories like Quantum Electrodynamics and Quantum Chromodynamics.

'Dark Matter and Other Elementary Particles' develops a spatial model of the elementary particles (e.g., proton, neutron, electron, quarks, nuclides, and mesons) for particle physics much as the 'ball and stick' model provides to chemistry.

This is a handbook, or an extended glossary, written in encyclopedic format, covering subjects around particle detectors, the underlying physics, and the analysis of their data. It is both introduction for newcomers and reference for physicists.
