Strong evidence that baryon junctions give the proton its identity

So, here’s a fascinating clue to why the visible Universe exists: protons and neutrons carry a conserved property called baryon number. The STAR Collaboration reports the strongest experimental evidence yet that this property is carried not by the quarks inside these particles, but by structures called baryon junctions that bind the quarks together. The result comes from nuclear collision experiments and gives fresh support to a long-standing idea about how the strong force holds baryons together. It brings scientists closer to understanding the basic ingredients of matter and the history of the early Universe.
