Improved ATLAS result weighs in on the W boson

The W boson, a fundamental particle that carries the charged weak force, is the subject of a new precision measurement of its mass by the ATLAS experiment at CERN.

Prototype particle detectors project smashes milestone

Carnegie Mellon University physicists in Pittsburgh are one step closer to building new particle detectors for the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider (LHC).

Preparing for a more powerful particle accelerator

The Large Hadron Collider at CERN is back in action after a three-year scheduled technical shutdown period. Experts circulated beam in the powerful particle accelerator at the end of April, and Run 3 physics started in early ...

Higgs10: Inventing the future of Higgs research

In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it was discovered at the ...

What comes after the Higgs boson

Ten years ago this week, two international collaborations of groups of scientists, including a large contingent from Caltech, confirmed that they had found conclusive evidence for the Higgs boson, an elusive elementary particle, ...

Large Hadron Collider revs up to unprecedented energy level

Ten years after it discovered the Higgs boson, the Large Hadron Collider is about to start smashing protons together at unprecedented energy levels in its quest to reveal more secrets about how the universe works.
