'Perfect liquid' quark-gluon plasma is the most vortical fluid

Particle collisions recreating the quark-gluon plasma (QGP) that filled the early universe reveal that droplets of this primordial soup swirl far faster than any other fluid. The new analysis of data from the Relativistic ...

Proton-nuclei smashups yield clues about 'quark gluon plasma'

Findings from Rice University physicists working at Europe's Large Hadron Collider (LHC) are providing new insight about an exotic state of matter called the "quark-gluon plasma" that occurs when protons and neutrons melt.

A view of the colorful microcosm within a proton

The proton sounds like a simple object, but it's not. Inside, there's a teeming microcosm of quarks and gluons with properties such as spin and "color" charge that contribute to the particle's seemingly simplistic role as ...

RHIC particle smashups find that shape matters

Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider (RHIC)-an "atom smasher" dedicated to nuclear physics research at the U.S. Department of Energy's Brookhaven ...

CERN collides heavy nuclei at new record high energy

The world's most powerful accelerator, the 27 km long Large Hadron Collider (LHC) operating at CERN in Geneva established collisions between lead nuclei, this morning, at the highest energies ever. The LHC has been colliding ...
