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 ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson National ...

Telltale signs of a lambda hyperon (Λ) decaying into a proton (p) and a pion (π-) as tracked by the Time Projection Chamber of the STAR detector. Because the proton comes out nearly aligned with the ...

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, ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Artist's illustration of a supermassive black hole shows a large circular black void on the right with swirls of blue, pink and ...

Scientists have discovered a common thread between the monstrous black holes that lurk at the hearts of galaxies and subatomic glass condensates created in collisions of atomic nuclei. When you ...
