Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles.

Scientists find a sub-atomic particle's mass is at odds with a theory underpinning modern physics.

Scientists have made new findings regarding the W boson, a fundamental particle, in a new research published in the Science journal. The study shows that it has a significantly greater mass than previously theorised in the Standard Model of particle physics. During the research, more than 400 scientists scrutinised four million W boson candidates out of a "dataset of around 450 trillion collisions" for over over 10 years.

The W boson is an electrically charged fundamental particle that governs one of the four fundamental forces of nature.

The W boson is an elementary particle involved in radioactive decay and nuclear fusion.

An ultraprecise measurement of the mass of the W boson may diverge from the Standard Model, a long-reigning framework that governs the strange world of quantum physics.

The particle, the W boson, has a significantly greater mass than set out by the Standard Model of particle physics, report scientists in Batavia, Illinois.

The team has found that the particle, known as a W boson, is more massive than the theories predicted

International scientists have taken the most precise measurement of the W boson to date – determining the mass of the W boson with a precision of 0.01%. The new measurement, published today in Science deviates from the W boson mass as predicted by ca

A team of 400 scientists have made a very precise measurement of the subatomic W boson - but it doesn't sit with the Standard Model of physics.
