Following the confirmation of the top quark discovery at the
Tevatron, the next step is to begin studying its properties. Because the
scale of electroweak symmetry breaking is of the same order as the measured
top mass, the top quark may be very sensitive to new physics. We describe
measurements of the total tt-bar cross section, the tt-bar invariant mass,
the top transverse momentum distribution, and single top production from Run
1 data at D0 and CDF. All of these measurements will become more precise in
Run 2.
