Title: Recent results on top quark physics at CDF

Conference ·
OSTI ID:572785

We present the latest results on the top quark obtained by the CDF experiment using a data sample of about 110 pb{sup -1}. The data sample has been collected at the FermiLab Tevatron Collider with p{anti p} collisions at {radical}s = 1.8 TeV. We briefly describe the candidate event selection and then discuss the production cross section determination and the mass measurement. Combining the results from the channels with at least one W decaying leptonically into an electron or muon, we measure {sigma}{sub t{anti t}} = 7.5{sup +1.9}{sub -1.6} pb. Our best measured value for the top mass gives M{sub t} = 176.8{+-}6.5 GeV/c{sup 2}. We also report on the observation of t{anti t} production in the all hadronic decay channel using kinematic selection and b identification, and in the channel containing one hadronically decaying {tau} lepton. Finally we discuss the kinematics of top events and measure the matrix element {vert_bar}V{sub tb}{vert_bar}=1.12{+-}0.12.
