After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest particle collider—has ...

For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996. "Proton emission is a rare form of ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

The CMS collaboration at CERN have searched for evidence of long-lived particles beyond the Standard Model in proton-proton collision events Despite the huge success of the Standard Model of particle ...
