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, ...

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 ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles ...
