The D-Zero Experiment is a worldwide collaboration of physics researchers centrally located at the Fermilab National Accelerator Laboratory's Tevratron Collider. The experiment focuses on the fundamental nature of matter, with particular attention paid to "precise studies of interactions of protons and antiprotons at the highest available energies." Researchers will be especially interested in the results section within which they can access summaries of new results, D-Zero results presented at 1999 summer conferences, Run II Fermilab Supersymmetry/ Higgs Workshop documents and summaries, and documents of work conducted by various Physics Groups working in specialized areas. The site also offers a technical section featuring information on experiment upgrades and computing, as well as contact information for experiment collaborators. Note, some areas are restricted to D-Zero collaboration members.
