"Top Production at the Tevatron"
I will present the latest results from CDF in the study of top
quark production. A little over a decade after the discovery of the
Top quark the Tevatron has now produced over 10 times the
statistics of the first experiment . Because of this, we are finally now able
to precisely test the top quarks place in the Standard Model. In
the same amount of time it took to collect this data, measurement
techniques have advanced at a similar pace. I will discuss two new
state-of-the-art measurements with the latest data of the top quark
cross section. These new measurements are the first to reach the
precision of the theoretical cross-section, and have managed to
resolve a long-standing discrepency between previous measurements.
In addtion, a new measurement, the forward backward asymmetry is
discussed. The measurement is a test of discrete symmetries at very
high energy, which has recently received a sizable amount of attention
because of an unexpectedly large measured value.
