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.
Study reveals that initial state conditions set up particle flow patterns, helping zero in on key properties of matter that mimics the early universe.
Theorists' hydrodynamic flow calculations accurately describe data from collisions of photons with lead nuclei at the ATLAS experiment.
Suppression of a telltale sign of quark-gluon interactions indicates gluon recombination in dense walls of gluons.
Quantum interference between dissimilar particles offers new approach for mapping gluons in nuclei, and potentially harnessing entanglement.
