"The origins and acceleration mechanisms of ultrahigh-energy cosmic rays have been among the biggest mysteries in the field ...

Physicists at CERN’s Large Hadron Collider have uncovered new hints that certain particle decays may not behave as the ...

A new study, published in the journal Physical Review Letters, suggests that some of the highest-energy cosmic rays could ...

Muons are a key subatomic particle in the discovery of new physics, but after particle collision, they’re difficult to track.

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...

GENEVA - Scientists at the world's biggest atom smasher hailed the discovery of "the missing cornerstone of physics" Wednesday, cheering the apparent end of a decades-long quest for a new subatomic ...

Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature. By combining a specially designed neural network with precise 3D tracking of ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, ...

Scientists at CERN have made a massive achievement after they began powering a 312-foot test stand for the High-Luminosity LHC (HL-LHC) upgrade, just several weeks after cooling the setup to absolute ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an ...
