Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Physicists at the world's ...

Several massive multimillion dollar experiments should soon reveal more about the nature of these ghostly particles ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

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 ...

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 ...

Researchers at Fermilab have made a measurement that could mean that scientists have to rethink their understanding of the rules that govern the subatomic world. Muons are ephemeral subatomic ...

GENEVA -- One of the very pillars of physics and Einstein's theory of relativity -- that nothing can go faster than the speed of light -- was rocked Thursday by new findings from one of the world's ...

A subatomic particle known as a muon is disobeying the basic laws of physics, according to preliminary results from two separate experiments debuted on Wednesday. The Muon g-2 experiment at the ...

GENEVA -- A pillar of physics -- that nothing can go faster than the speed of light -- appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert ...
