Explain it in 60 Seconds: Lattice QCD

07/25/24

Lattice gauge theory, or lattice QCD, is a calculation method that helps scientists make predictions about the behavior of quarks at low energies.

CERN cafeteria

Walk into the main CERN cafeteria at various times of the day and you'll find different scenes: scientists discussing results over coffee; a parent coaxing his children to finish lunch before swooping them back to the nursery school on site; groups of grad students soaking up the sun on the

Looking for leptons in all the right places

In a typical high school physics textbook, says scienceeducation specialist Beth Marchant, only the last chapter is devoted to all the developments since 1900–the stuff that physicists are actually working on today.

First vertex detector

The Positron Electron Project (PEP) collider at the Stanford Linear Accelerator Center produced its first collisions in 1979. All sorts of particles burst out, including the tau lepton, an ephemeral cousin of the electron.

A top gradient for cleanliness

After undergoing a buffered chemical polishing (BCP) treatment at Cornell University, the first US-processed and tested International Linear Collider superconducting cavity achieved a milestone accelerating gradient of 26 MV/m (megavolts per meter)–surpassing the first gradient goal (25 MV/m).

Spallation Neutron Source

Neutron scattering research has improved the quality of many everyday items: Shatter-proof windshields, credit cards, pocket calculators, airplanes, compact discs, and magnetic storage tapes are just some examples.

Particle physics takes flight

Welcome to SLAC's End Station B, where work on the International Linear Collider (ILC) will help shape the future of particle physics–although some inhabitants don't seem to give a hoot.
