Abstract:

The top quark, by far the most massive particle in the Standard Model, was discovered only ten years ago at the Tevatron collider at Fermilab. Now, as our analysis tools improve and statistical limitations begin to disappear, we have reached a new level of precision in the determination of top's properties. I will describe a recent measurement of the top pair production cross section at CDF in events with one final-state lepton and one or more identified bottom-quark jets, the world's best cross section measurement to date.
