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 ...

An MIT-led team has found that data from “near-misses” at the Large Hadron Collider, long dismissed as background noise, can be mined for rare photon-photon interactions that test the boundaries of ...

When it comes to particle physics, Tova Holmes has been there, done that and got the T-shirt – in fact, she designed the T-shirt herself. It all started back in 2022, when she and a few colleagues ...

Last summer, a wedding photographer walked begrudgingly into a physics laboratory outside Rome. Feeling uninspired by the intricate machinery around him, he decided to turn off the lights. “I wanted ...

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 ...

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 ...

Recently, nanoscale pn-junction rings have been introduced as a vehicle for confinement of electronic states in Dirac materials [1]. Confined states in these Dirac quantum dots arise due to ...

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.

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 ...

"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 ...

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 ...
