The DØ Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the Tevatron Collider, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe.
The DØ experiment is one of two large collider experiments based at the Fermilab Tevatron. DØ and its sister experiment CDF jointly discovered the top quark.
The DØ experiment is made of several technologies, ranging from a silicon and optical fiber tracker, surrounded by a calorimeter that includes uranium and liquid argon and finally a system designed to measure muons.
The DØ collaboration is formed by about 600 physicists consisting of 89 institutions from 18 countries around the world.
