At CERN, US scientists work with an international community to answer the biggest questions in particle physics: the study of fundamental particles and forces.

What is CERN?

CERN is an international laboratory for particle physics research. The laboratory provides the infrastructure and resources for autonomous experiments.

The United States was awarded CERN observer status in 1997 for significant in-kind contributions to CERN's accelerator complex. The US-CERN collaboration is governed by international cooperation agreements, which are prepared and agreed upon jointly by the US Government agencies and CERN.

More than 2100 users from US institutes are registered at CERN, making the United States the lab's largest user community.

US scientists are full members of the experiments hosted at CERN and hold many leadership positions within the scientific collaborations.

A machine like no other

The Large Hadron Collider—the world's most powerful particle accelerator—is CERN's flagship program.

It smashes atoms at almost the speed of light, revealing the inner workings of subatomic particles.

US researchers and engineers designed and built crucial portions of the LHC and are involved in all four major LHC experiments: ATLAS, CMS, ALICE and LHCb.

Today, US researchers are building new accelerator magnets and detector components for the High-Luminosity LHC, an upgrade that will increase the collision rate by a factor of four.

A historic agreement

The United States and CERN are partnering on the Long-Baseline Neutrino Facility and the Deep Underground Neutrino Experiment, a new mega-science project hosted by Fermilab in the United States.

The detector R&D performed at the CERN Neutrino Platform will serve as the blueprint for DUNE. CERN will also build cryostats and other components for the final facility and experiment.

This is the first time CERN is contributing expertise and resources to an experiment located outside Europe.
