The U.S. nuclear physics community is preparing to build the electron–ion collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter ...

What does quark-gluon plasma -- the hot soup of elementary particles formed a few microseconds after the Big Bang -- have in common with tap water? Scientists say it's the way it flows. What does ...

Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins align ...

Suppression of a telltale sign of quark-gluon interactions indicates gluon recombination in dense walls of gluons. Previous experiments have shown that when ions are accelerated to high energies, ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

Scientists at the Relativistic Heavy Ion Collider (RHIC) have found new evidence that collisions of small nuclei with large ones can create tiny specks of quark-gluon plasma (QGP), a state of matter ...

Holographic QCD employs ideas drawn from string theory and the AdS/CFT correspondence to study the strong coupling regime of quantum chromodynamics, offering a dual gravitational description of quark ...
