Top Physics Results from Cdf

The top quark is by far the most massive fundamental particle observed so far, and the study of its properties is interesting for several reasons ranging from its possible special role in electroweak symmetry breaking to its sensitivity to physics beyond the Standard Model. We present recent top physics results from CDF based on 160-320 pb −1 of p¯ p collision data at √ s = 1.96 TeV. The t ¯ t cross section and the top mass have been measured in different decay channels and using different methods. We have searched for evidence of single top production, setting upper limits on its production rate. Other results shown in this conference include studies of the polarization of W bosons from top decays, a search for charged Higgs decaying from top, and a search for additional heavy t ′ quarks.
