A pair of top quarks has been detected in the detritus spraying forth from the collision of two atoms of lead. This means that we're a step closer to taking new measurements of this primordial soup, ...

Frank Geurts is a professor of physics and astronomy at Rice and co-spokesperson of the RHIC STAR collaboration. A research team led by Rice University physicist Frank Geurts has successfully measured ...

New data from particle collisions at the Relativistic Heavy Ion Collider (RHIC), an "atom smasher" at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, reveals how the primordial ...

According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense "soup" composed of freely moving quarks and ...

Schematic of cosmic evolution. Credit: J. Phys.: Conf. Ser. 454 012051 Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have proposed a key indicator ...

New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot ...

For 30 years, physicists around the world have been trying to reconstruct how life-giving particles formed in the very early universe. ALICE is their mightiest effort yet. By Rahul Rao Published Aug ...

QGP is conventionally described using relativistic hydrodynamic models and studied experimentally through heavy-ion collisions. There has been a long-standing discrepancy between theory and experiment ...

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 ...

Scientists reveal correlated flow of particles emerging from even the lowest-energy, small-scale collisions at Big-Bang particle collider. Particles emerging from even the lowest energy collisions of ...
