We summarize results of some crucial measurements of the top quark and W/Z boson properties carried out by the D0 and the CDF collaborations at the Tevatron collider at Fermilab based on data collected during Run 1 (1992-96). Among the…
In 1995, the top quark was discovered at the Fermilab Tevatron Collider by the CDF and D0 collaborations in the ppbar collisions at sqrt(s)=1.8 TeV using about 50pb^-1 of data per experiment. We present the studies of the top quark…

The CDF and D0 collaborations at Fermilab's Tevatron p-pbar collider have in place an extensive program to measure fundamental properties of the top quark. Recent results from Run I (sqrt-s = 1.8 TeV) and Run II (sqrt-s = 1.96 TeV) on the…
An overview of the recent measurements of the top antitop quark pair production cross section in proton antiproton collisions at \sqrt{s}=1.96 TeV in lepton + jets and dilepton final states is presented. These measurements are based on 1 --…
Preliminary results on the measurement of four selected properties of the top quark are presented. The relative fraction of $t\bar{t}$ production through gluon fusion has been measured in the $t\bar{t}$ dilepton decay channel by the CDF…
We present a measurement of the ratio of the top-quark branching fractions $R=\mathcal{B}(t\rightarrow Wb)/\mathcal{B}(t\rightarrow Wq)$, where $q$ represents quarks of type $b$, $s$, or $d$, in the final state with a lepton and hadronic…
