In the 1980s, scientists discovered that a proton's three valance quarks (red, green, blue) account for only a fraction of the proton's overall spin. New measurements from RHIC's PHENIX experiment reveal that gluons (yellow corkscrews) contribute as much as or possibly more than the quarks.06.06.16Science Highlight

Zooming in on Gluons' Contribution to Proton Spin

New data that "wimpy" gluons, the glue-like particles that bind quarks within protons, have a big impact on proton spin. Read More »
