Looking inside trillion degree matter with ATLAS at the LHC

Stars, planets, animals, plants, you and me – everything that can be directly observed in our Universe is ordinary matter. But the Universe didn’t always look this way. This ATLAS feature describes the quark-gluon plasma, a unique state of matter that existed shortly after the Big Bang. The nature and properties of this matter are being revealed at CERN’s ATLAS Experiment.

Searching for Dark Matter with the ATLAS detector

When we look around us, at all the things we can touch and see all of this is visible matter. And yet, this makes up less than 5% of the universe.

The Higgs boson: the hunt, the discovery, the study and some future perspectives

Many questions in particle physics are related to the existence of particle mass. The “Higgs mechanism,” which consists of the Higgs field and its corresponding Higgs boson, is said to give mass to elementary particles.
