Muons are one of the key subatomic particles for discovering new physics, but tracking them after particle collisions can be difficult and prone to error. A new study ...

Look alive, science fans — a new subatomic particle has just dropped after a 20-year search. Discovered by British researchers at the nuclear research laboratory CERN near Geneva, Switzerland, the ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

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 ...

Our planet is under a constant bombardment of radiation—from space. Well, maybe it’s not as scary as that makes it seem. “Radiation” is a catchall term astronomers use for forms of light—including ...
