Latest about Particle Physics

The CDF detector, which is part of the Tevatron particle accelerator at Fermilab in Illinois, just stunned physicists with new “hefty” measurements of the W boson’s mass.

Oddly heavy particle may have just broken the reigning model of particle physics

By Paul Sutter last updated

An ultraprecise measurement of the mass of the W boson may diverge from the Standard Model, a long-reigning framework that governs the strange world of quantum physics.

What is the Standard Model, the subatomic physics theory that has been tested more than any other?

By Paul Sutter published

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.

Ultraprecise atomic optical clocks may redefine the length of a second

By Tia Ghose published

The length of a second hasn't been updated in 70 years, but ultraprecise atomic optical clocks are on track to change that.

Here, the Large Hadron Collider is shown on April 22, 2022, the day the atom smasher restarted again for Run 3 after a three-year nap.

What is the Large Hadron Collider?

By Adam Mann published

The Large Hadron Collider is the world's most powerful particle accelerator. Here's a look at the atom smasher and all its amazing discoveries.

Large Hadron Collider is waking up after a 3-year nap, and it could help explain why the universe exists.

By Mara Johnson-Groh published

After a three-year nap, the world's largest atom smasher is waking up and getting ready to smash atoms harder than ever.
