**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

**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.
