CERN

Nearly a mile underground in South Dakota, scientists are building a world-leading experiment to study neutrinos and investigate some of the universe’s greatest mysteries, including how the universe took shape after the Big Bang and if neutrinos are the reason our world is predominantly made of matter. Currently, crews from Fermilab, CERN and SURF are assembling large steel beams to form the outer structure of the neutrino experiment’s massive detector modules.

Crews at the Sanford Underground Research Facility have moved about 39% of the I-beam steel needed to construct the cryotat for the Deep Underground Neutrino Experiment. That represents nearly 2 million pounds of steel that completely fills the south cavern that is 500 feet long, 65 feet wide, and about 7 stories tall.

Fermilab recently hosted over 500 physicists for the American Physical Society’s biennial Division of Particles and Fields meeting. With presentations by Fermilab Director Norbert Holtkamp and CERN Director-General Mark Thomson, the meeting provided particle physicists the opportunity to come together and consider the future of high-energy physics research.

A prototype for the world’s biggest neutrino experiment is running under extreme conditions to see how well the technology performs under pressure.

Fermilab Distinguished Scientist Patricia McBride was invited to Santa Monica, California to accept the 2025 Breakthrough Prize in Fundamental Physics on behalf of the CMS collaboration.

As upgrades enable the LHC to produce more and more particle collisions, physicists are using machine learning to keep up with the growing task of sorting through everything.

About 1,400 people attended the grand opening of CERN’s new science education center.

Results from the ALPHA experiment confirm that matter and antimatter react to gravity in a similar way.

In a race against the clock, CERN engineers and technicians pulled together to find and fix a leak inside the Large Hadron Collider.

Building upon agreements signed in 2017 and 2021, the new signing with Fermilab details CERN’s contributions to the international Deep Underground Neutrino Experiment, which will be the world’s most comprehensive neutrino experiment.
