Spin and Orbital Angular Momentum of Quarks and Gluons in the Nucleon
→
Europe/Rome
Description
Understanding the internal structure of the proton is a crucial challenge for QCD, and one important aspect of this is to understand how the spin of the nucleon is built up from the angular momentum of its quarks and gluons. This, it has turned out, is a very subtle and controversial issue.
The aim of this workshop is to bring together the main actors in the field of the proton spin decomposition to summarize the recent progress and discuss the remaining controversial points.
