Present understanding of the nucleon spin structure
arXiv:hep-ph/0412156 · doi:10.1142/9789812701909_0001
Abstract
The present understanding of the spin structure of the nucleon is briefly reviewed. The main focus is on parton helicity distributions, orbital angular momentum of partons as defined through generalized parton distributions, as well as single spin asymmetries and time-reversal odd correlation functions.
