Scientists use high-energy heavy ion collisions in a new way to reveal subtleties of nuclear structure with implications for many areas of physics.
Particles of light from collisions of deuterons with gold ions provide direct evidence that energetic jets get stuck.
A new approach to applying quantum chromodynamics paves the way for a deeper understanding of the strong nuclear interaction.
Recent advances enable simulations near a possible critical endpoint of the transition between the quark gluon plasma and a hadron liquid.
Scientists use a large-scale statistical analysis to extract the viscosity of hot, dense nuclear matter created at different heavy ion collision energies.
Data from heavy ion collisions give new insight into the electromagnetic properties of quark-gluon plasma “deconfined” from protons and neutrons.
A measurement tracking ‘direct’ photons from polarized proton collisions points to positive gluon polarization.
Theorists predict differential distribution of 'up' and 'down' quarks within protons—and differential contributions to the proton's properties.
New results will help physicists interpret experimental data from particle collisions and better understand the interactions of quarks and gluons.
New calculations suggest that high energy quarks should scatter wider and faster in hot quark matter than can be accounted for by local interactions.
First measurements of how hypernuclei flow from particle collisions may give insight into the strange matter makeup and properties of neutron stars.
New measurements at RHIC provide evidence for quark ‘deconfinement’ and insight into the unimaginable temperature of the hottest matter on Earth.
