A key theory of particle physics, the Standard Model has withstood test after test. But there are holes in the theory, particularly when it comes to gravity.

The Standard Model of Particle Physics is the collection of discoveries and theories that describe the smallest units of matter and the interactions between energy and matter. According to this model, ...

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them.

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 ...

The Standard Model of Particle Physics is a remarkable scientific achievement spanning nearly a century, and its predictive power has proven incredibly consistent.

Since it was developed in the 1970s, the Standard Model of particle physics has been extremely successful at explaining the interactions of particles and most fundamental forces.

An experiment with a single electron, trapped for months on end, produced one of the most precise tests yet of the standard model of particle physics.

There are also rumblings through other sectors of particle physics, like neutrino research, of observations of particle behavior not quite adding up with the Standard Model’s predictions.

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 ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find.

But recent results hinting at unexplained new physics beyond the standard model are of this second type. Detailed studies from the LHCb experiment found that a particle known as a beauty quark ...
