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 ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...

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 ...

Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists have pinned down a property of ...
