Living on: data taken by the now defunct CDF experiment has revealed a surprising mass for the W boson. (Courtesy: Fermilab) The most precise measurement to date of the mass of the W boson has yielded ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

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 ...

The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, ...

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 ...

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 ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

The model we have for understanding the universe’s fundamental particles is a bit like a gearbox: one tiny change to any one single particles’ properties throws off the mechanics of the other ...

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 ...
