A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny ...

Physicists report new evidence that production of an exotic state of matter in collisions of gold nuclei at the Relativistic Heavy Ion Collider (RHIC) can be 'turned off' by lowering the collision ...

Very soon after the Big Bang, the universe enjoyed a brief phase where quarks and gluons roamed freely, not yet joined up into hadrons such as protons, neutrons and mesons. This state, called a ...

Exploring the gluon saturation in a large nucleus is one of the goals of the future Electron-Ion Collider. Researchers proposed a nucleon energy-energy correlation approach that provides a unique ...

Stony Brook University physicists Gabor David and Axel Drees sketch out how a signal of jet energy loss in deuteron-gold collisions at the Relativistic Heavy Ion Collider (RHIC) supports the case that ...
