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 ...

If you want to explain what was and what is, you need particle physics. Because everything we see consists of molecules and atoms, and atoms in turn consist of atomic nuclei and electrons. The atomic ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

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 ...

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 ...

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them. When you purchase through links on our site, we may earn an ...

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 ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Roger Jones receives funding from STFC. I am a member of the ATLAS Collaboration As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is ...
