Abstract

The Tevatron proton-antiproton collider at Fermilab with its centre of mass energy of 1.96 TeV is currently the only source for the production of top quarks. Its increased luminosity and centre of mass energy in Run II allow both collider detectors CDF and D0 to study top quarks with unprecedented scrutiny. Recent results on the top quark's pair production cross section and its properties such as mass, electric charge, helicity of the W boson in its decay and branching fraction B(t->Wb) are presented and probe the validity of the Standard Model.
