The angular momentum controversy: What's it all about and does it matter?
by

Publisher: arXiv
Number of pages: 96

Description:
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.
