Abstract
The discovery of the top quark in 1995, by the CDF and DO collaborations at the Fermilab Tevatron, marked the dawn of a new era in particle physics. S ince then, enormous efforts have been made to study the properties of this remarkable particle, especially its mass and production cross section. In t his article, we review the status of top quark physics as studied by the tw o collaborations using the p (p) over bar collider data at root s = 1.8 TeV . The combined measurement of the top quark mass, m(t) = 173.8 +/- 5.0 GeV/ c(2), makes it known to a fractional precision better than any other quark mass. The production cross sections are measured as sigma(t (t) over bar) = 7.6(-1.5)(+1.8) pb by CDF and sigma(t (t) over bar) = 5.5 +/- 1.8 pb by DO . Further investigations of t (t) over bar decays and future prospects are briefly discussed.
