Scientists seeking to explore the teeming microcosm of quarks and gluons inside protons and neutrons report new data delivered by particles of light. The light particles, or photons, come directly ...
Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...
Nuclear physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have new evidence that particles called gluons reach a steady 'saturated' state inside the speeding ions.
