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 ...

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 ...

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 ...

Electrons are still almost perfectly round, a new measurement shows. A more squished shape could hint at the presence of never-before-seen subatomic particles, so the result stymies the search for new ...

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 ...

Physicists should be ecstatic right now. Taken at face value, the surprisingly strong magnetism of the elementary particles called muons, revealed by an experiment this month, suggests that the ...

IN 1973, physicist Steven Weinberg gave a talk in Aix-en-Provence, France. It was there, according to Weinberg, that he first used the term “standard model” to describe the nascent description of the ...
