Muons are elementary particles that resemble electrons, but they are heavier and decay very rapidly (i.e., in just a few microseconds). Studying muons can help to test and refine the standard of ...

Scientists sometimes make bold claims about where their research might lead, but the most weighty assertions are usually scaled back or forgotten entirely as new data becomes available. Several years ...

NEW YORK – Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely -- but that's still good news for the laws of physics as we know ...
