The DØ Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the world's premier high-energy physics laboratory 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 provided by the Tevatron collider. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe. The DØ experiment finished data collection in 2011 when the Tevatron collider run ended and now is analyzing the collected data set.
