ABSTRACT:
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.
