The nucleon spin decomposition: news and experimental implications
arXiv:1401.3954 · doi:10.1051/epjconf/20147302005
Abstract
Recently, many nucleon spin decompositions have been proposed in the literature, creating a lot of confusion. This revived in particular old controversies regarding the measurability of theoretically defined quantities. We propose a brief overview of the different decompositions, discuss the sufficient requirements for measurability and stress the experimental implications.
