So-called “XYZ states” defy the standard picture of particle behavior and have given rise to several attempts to understand ...

When we go backwards in time through the history of the cosmos, the distances and volumes shrink, while the average energy ...

The Large Hadron Collider (LHC) is like an immensely powerful kitchen, designed to cook up some of the rarest and hottest ...

Observing critical fluctuation in a heavy ion collision would mark the first direct observation of a phase change between the ...

A recent study has proposed a new mechanism for the formation of primordial black holes that could provide answers about dark matter.

“We’re looking at matter that’s pushed to its absolute limits,” Broodo said. “Once you figure that out, you have potentially ...

An elusive particle that first formed in the hot, dense maelstrom of the early universe has puzzled physicists for decades.

Hybrid model A new description of nuclei combines the quark–gluon model of particle physics with the proton–neutron ...

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC) to reveal subtle details about the shapes of atomic nuclei. The method is ...

This book introduces quark gluon-plasma (QGP) as a primordial matter composed of quarks and gluons, created at the time of the "Big Bang". After a pedagogical introduction to gauge theories, various ...

Scientists at Brookhaven National Laboratory have used supercomputer simulations to predict electric charge distributions in ...
