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

Muon colliders could slam the subatomic particles together in hopes of unlocking physics secrets. Giving muons a speed boost is a crucial step.

So-called “XYZ states” defy the standard picture of particle behavior and have given rise to several attempts to understand their nature. But researchers with the Center for Theoretical and ...

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

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

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

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 ...

Nuclear physics theorists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have demonstrated that ...

The Big Bang theory suggests that the universe began as a hot, dense point, expanding into the cosmos we observe today.

Atomic nuclei, composed of protons and neutrons, hide quarks and gluons at their core. These latter particles, still challenging to study, have long eluded scientists. In the mid-20th ...

A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the ...
