Photon-deuteron collisions offer insight into the gluons that bind the building blocks of matter—and what it takes to break protons and neutrons apart.
Scientists find strong evidence for the long-predicted Breit-Wheeler effect—generating matter and antimatter from collisions of real photons.
Nuclear scientists devise an indirect method of measuring the speed of sound in matter created in heavy-ion collisions.
Measurements of particle “flow” and hot matter created in low-energy collisions provide key data in understanding nuclear phase transition.
Fluctuations in data from collisions of gold nuclei hint at a possible ‘critical point’ in how nuclei melt.
Scientists predict that gluons, the particles that bind quarks, also bind to one another, but they have never unambiguously observed globs of pure ‘glue.’
Tracking particles containing charm quarks offers insight into how quarks combine.
New measurements offer insights into binding interactions that glue fundamental building blocks of matter together.
Team combines many innovative accelerator accomplishments to keep gold ions cold and advance nuclear physics research.
Diagnostic test will improve performance of collider as physicists explore sources of proton spin
Low-momentum (wimpy) quarks and gluons contribute to proton spin, offering insights into protons’ behavior in all visible matter.
The spin direction of protons was reversed, for the first time, using a nine-magnet device, potentially helping tease out details about protons that affect medical imaging and more.
