“In a GHZ state, if you measure one qubit, the whole superposition collapses. But in a W state, even if you measure one ...

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 ...

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 ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run.

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 ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...
