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.
Calculations predict the temperature at which bottomonium melts in the hot matter created in heavy ion collisions.
Data on protons emitted from wide range of gold-gold collision energies shows absence of a quark-gluon plasma (QGP) at the lowest energy.
Spin orientation preference may point to a previously unknown influence of the strong nuclear force—and a way to measure its local fluctuations.
