The famed collider at Brookhaven National Laboratory has ended operations, but if all goes to plan, a new collider will rise ...

For a mere moment after the Big Bang, no neutrons or protons are thought to have existed. These neutral and positively charged particles, respectively, make up the center of all atoms today. But ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.

At Brookhaven National Laboratory on Long Island, the Relativistic Heavy Ion Collider has powered down for the last time, ...

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

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

US physicists have shed light on a long-standing mystery after they captured rare experimental ...

The Relativistic Heavy Ion Collider , the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set ...

Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...

Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a ...

A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to ...
