Physicists discover a hidden gluon structure inside protons that could rewrite textbooks

SMRTR summary

Physicists at RHIC discovered that gluons, not quarks, may carry a proton's baryon number through a Y-shaped "gluon junction." Experiments showed twice as many baryons as quark-stopping models predicted, suggesting this junction transports baryon number independently. This challenges textbook physics and could reshape understanding of matter's fundamental stability.
