CERN’s ATLAS Collaboration Confirms Quark-Gluon Plasma Acts as a Single, Expanding Fluid
Physicists from Brookhaven National Laboratory and Stony Brook University leading the ATLAS Collaboration at CERN have confirmed the quark-gluon plasma’s radial flow is a collective behavior, driven by fireball size. This provides a new way to measure the perfect liquid’s bulk viscosity, probing properties of the early universe.
