A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles.

Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?

The LHCb experiment at CERN has discovered three new ‘pentaquark’ particles being created in high energy particle collisions at the Large Hadron Collider.

What shape is an electron? The answer, believe it or not, has implications for our understanding of the entire universe, and could reveal whether there are mysterious particles still to be discovered.

The Large Hadron Collider has generated mind-blowing science in the last decade – including the Higgs boson particle. Why is the LHC so important, and how will physicists use it in the years to come?

Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
CERN isn’t only breaking ground in physics, but also in open access to science.

It’s not enough to do groundbreaking research if the results are kept from the public. So CERN is making its results available to everyone via open access, showing how science should be done.

Particle accelerators are helping to push forward the frontiers of theoretical physics but they’ve also had more impact on your everyday life than you realise.
Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.
You can feel the weight of an object on Earth because of its mass. But what is mass?

We talk about mass all the time but what is it that actually gives an object mass? And why do some things have mass and others have no mass at all?
