The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find. When you purchase through links on our site, we may earn ...

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force. When you purchase through links on ...

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 ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

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 ...
