A controversy has arisen as to how to define quark and gluon angular momentum, important in understanding the internal structure of the nucleon. For a review of the controversy, see [1]. I survey some of the ideas put forward and try to assess their physical implications.

• Transverse and longitudinal angular momenta of light (2015, background): “However, it turns out that the more relevant and directly measurable quantity is the so-called canonical (or orbital) momentum density [14,30,34,50,54,89,92], which appears in canonical Noether conservation laws (in the Coulomb gauge) in electromagnetic field theory [23,34,37,38].”
