Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results, further solidifying the experimental world average. Scientists working on ...

On April 7, particle physicists all over the world were excited and energized by the announcement of a measurement of the behavior of muons—the heavier, unstable subatomic cousins of electrons—that ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

A U.S. research lab has announced one of the most precise measurements ever of how a subatomic particle behaves, teeing up a showdown that could either vindicate one of science’s most powerful ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...

As far as astronomers can tell, the universe is continuing to expand — and our understanding of how it is doing this needs to expand as well. In fact, recent findings from researchers partnering with ...
