The ins and outs of quantum chromodynamics

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

Revealed: Positronium's behavior in particle billiards

Collision physics can be like a game of billiards. Yet in the microscopic world, the outcome of the game is hard to predict. Fire a particle at a group of other particles, and they may scatter, combine or break apart, according ...

World's largest particle collider busts record

The world's largest particle smasher broke the record for energy levels late Wednesday in a test run after a two-year upgrade, CERN announced Thursday.

Explainer: What are fundamental particles?

It is often claimed that the Ancient Greeks were the first to identify objects that have no size, yet are able to build up the world around us through their interactions. And as we are able to observe the world in tinier ...

Experiment brings precision to a cornerstone of particle physics

In a paper published yesterday in the journal Physical Review Letters, the COMPASS experiment at CERN reports a key measurement on the strong interaction. The strong interaction binds quarks into protons and neutrons, and ...

New analysis shows a way to self-propel subatomic particles

Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.

On the front lines of the Higgs boson search

Finding the Higgs boson at CERN involved an exciting chain of events and sharing it with the wider public through the media was also a journey of discovery, Prof. Jon Butterworth told an audience at the IOP's London centre ...
