science ⚛️ Gluons, not quarks, carry baryon number in collisions
New data from the STAR detector at RHIC suggests that gluons, not just quarks, transport the baryon number during particle collisions. This research, published in Science, focuses on the Y-shaped gluon junction linking protons' three main quarks. The findings challenge the traditional idea that only the three valence quarks bear the baryon number. This conservation principle is vital as it keeps the total count of baryons constant across the universe. Scientists will now investigate how this gluon-based transport fits into QCD models. ⚛️
