Physics with b-Quarks at the Tevatron

The Fermilab Tevatron proton-antiproton collider is the highest energy collider in the world, and will remain so until 2008, when the LHC at CERN turns on. Run II at the Tevatron is underway. Commissioning of the DZero experiment is nearing completion and the DZero detector is now collecting physics-quality data. In this talk, the Dzero experiment will be briefly described. The Silicon Track Trigger, a novel device for triggering on displaced tracks from b-quark decays, will be presented. The b-quark physics program at DZero will be discussed and recent results will be shown. Prospects of the B physics potential of DZero over the next few years will be illustrated, as will be the possibility of discovering the Higgs boson at the Tevatron.
