There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

“You can do it quickly, you can do it cheaply, or you can do it right. We did it right.” These were some of the opening remarks from David Toback, leader of the Collider Detector at Fermilab, as he ...

The battle over the heft of a hard-to-detect particle is heating up. What’s at stake? Only the leading theory describing all known matter in the universe. A recalculation of the mass of an elementary ...

The Standard Model of Particle Physics has withstood rigorous test after test over many decades, and the discovery of the Higgs boson in 2012 provided the last observational piece of the puzzle. But ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. The sun, a nuclear power plant, and carbon dating all draw their ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. The giant Compact Muon Solenoid experiment at the LHC. The different rings of detectors, arranged ...

Physicists on the CMS experiment announce the most elaborate mass measurement of a particle that has captivated the physics community for decades. Following up on an unexpected measurement by the ...

A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. The measured value shows tension with the value expected based on ...

It is once again stocky particle spring. You might recall that, one year ago, researchers at Fermilab announced the discovery of a fat wobbly muon. Now, they have another offering for us: a boson with ...
