Super strong magnetic fields leave imprint on nuclear matter

A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the ...

Research reveals quantum entanglement among quarks

Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment ...

A dense quark liquid is distinct from a dense nucleon liquid

Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves ...

Not all jets radiate equally in quark-gluon plasma, study finds

Studying nuclear matter under extreme conditions allows scientists to better understand how the universe might have looked right after its creation. Scientists at the Large Hadron Collider achieve the conditions for recreating ...

Exotic atomic nucleus sheds light on the world of quarks

Experiments at CERN and the Accelerator Laboratory in Jyväskylä, Finland, have revealed that the radius of an exotic nucleus of aluminum, 26mAl, is much larger than previously thought. The result, described in a paper just ...

LHCb: Correlations show nuances of the particle birth process

High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born ...

The quark model: A personal perspective

The idea that protons and neutrons were composed of even smaller particles, with non-integral electric charges, was proposed in 1963/64 by Andre Petermann, George Zweig and Murray Gell-Mann, who dubbed them "quarks." It was ...
