Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

The Large Hadron Collider (LHC) is in the business of discovering new subatomic particles—and business is good. The team at CERN recently announced the discovery of a new particle, named Ξcc⁺ or Xi-cc ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel ...

A pair of rare particles produced in high-energy proton collisions may be the clearest evidence yet that mass can emerge from empty space. The finding could shed light on one of the biggest puzzles in ...

"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles ...

Here’s what you’ll learn when you read this story: The Large Hadron Collider (LHC) is in the business of discovering new subatomic particles—and business is good. The team at CERN recently announced ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure of the entire universe. Scientists are getting close to figuring out how.
