Theory and Experiment Combine to Shine a New Light on Proton Spin

A recent study reveals new details of the origins of the proton’s spin

NEWPORT NEWS, VA – Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a new method that combines experimental data with state-of-the-art calculations has revealed a more detailed picture of spin contributions from the very glue that holds protons together. It also paves the way toward imaging the proton’s 3D structure.
