The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

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 ...

A Cornell University physicist is among an international group of researchers recognized with one of science’s most ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

The nature of dark matter is largely unknown, but it is thought to have mass, which influences particle interactions in the universe through gravity. Dark matter may not interact much with visible ...

WASHINGTON (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...

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 ...
