Scientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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 ...

Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists have pinned down a property of ...

Two new subatomic particles whose existence was predicted by Canadian particle physicists have been detected at the world's largest particle collider. The discovery of the particles, known as Xi_b'- ...
