Particle Physics Division


The Fermilab Particle Physics Division advances the understanding of matter, energy, space and time by managing resources and providing support for researchers who conduct scientific research at the intensity, energy, and cosmic frontiers of high energy physics.

Fermilab and the LHC


For almost two decades, Fermilab and its scientists have played a significant role in the LHC and particularly in the CMS experiment. Fermilab also provides scientific, technical and organizational support for the 630 scientists and graduate students from 47 US universities and laboratories that participate in the 2,600-member international CMS collaboration.



Particles called muons could help scientists see hidden or rare processes in the subatomic realm.

Dark Matter and Dark Energy


Fermilab scientists were some of the first to bring together the worlds of astrophysics and particle physics to study topics such as dark matter and dark energy.



The advancement of particle physics research depends on the partnership between theory and experiment.
