The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...

Scientists at the University of Illinois Urbana-Champaign have confirmed the existence of a massless particle, long theorized ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

Several massive multimillion dollar experiments should soon reveal more about the nature of these ghostly particles ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists announced on Wednesday that they have found no evidence for the hypothetical “sterile neutrino,” an extra version of ...

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To ...

Jason Bono was one of the researchers behind a major scientific moment — when tiny particles unexpectedly unraveled one of the most important and successful theories in physics. Bono, who earned his ...

Astrid Eichhorn spends her days thinking about how the laws of physics change at the tiniest scales. Imagine zooming in closer and closer to the device on which you’re reading this article. Its ...

The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate why matter prevails over antimatter. This knot hypothesis, originally ...
