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 ...

Using high-intensity lasers, researchers have taken an important step toward miniaturization of particle accelerators by demonstrating free-electron laser amplification at extreme ultraviolet ...

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 ...

A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from the early universe. Scientists suggest these black holes could carry a ...

Scientists shot lasers at a semiconductor nano-lasagna to show how electrons behave. In the right conditions, the electrons became polarons, dragging oppositely-charged atoms along for the ride. The ...

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 ...
