This evidence for diboson production at DZero is an important test of the analysis techniques that are used to search for the Standard Model Higgs Boson. On May 22, 1969, the Apollo 10 Lunar Module dipped to just 47,400 feet above the lunar surface during the “dress rehearsal” for the following mission that landed mankind on the moon two months later. The Apollo 10 mission collected the final data needed to calibrate the lunar module’s guidance systems for a moon…

DZero physicists use the behavior of the single top quark like a telescope to look for new physics beyond the Standard Model. Cranking up the energy of colliding particles isn’t the only way to search for new physics. The Standard Model predicts very specific behavior from each particle that we’ve observed and strictly defines the ways those particles interact. Precision tests of that behavior allow us to probe for physics beyond the Standard Model. In that search, top quarks are…

The birth of the short-lived top quark affords DZero physicists the opportunity to study fundamental aspects of naked quarks. The birth of a top quark heralds an opportunity unique among the quarks—the chance to study a naked quark. Being so massive that it would fall just a few spots below gold on the periodic table, the top quark’s lifetime is very short. It never has time to join with other quarks to form hadrons, composite particles of quarks held together…

The lifetime performance of the Tevatron is tracked by the integrated luminosity, a measure of the number of particles delivered to the interaction region at DZero. Carl Sagan, renowned astrophysicist, expounded on the wonders of outer space in his television series Cosmos, explaining the vastness of our own galaxy, which contains billions upon billions of stars, and how it is just one of tens of billions of galaxies in the observable universe. These numbers are mind-bogglingly large, but such is…
