Top production and decay at CDF
We report on the measurement of top production and decay properties obtained by the CDF experiment with {ital p{anti p}} collisions at {radical}{ital s} = 1.8 TeV. the analyses presented here refer to {integral}{ital Ldt}{approx} 110 {ital pb}{sup -1} collected at the Fermilab Tevatron collider. About 85% of the possible {ital t{anti t}} decays have been studied in different channels according to the number of high-{ital p{sub T}} leptons found in the final state. Combining the results from the channels with at least one {ital W} decaying leptonically into an {ital e} or {mu} we measure {delta}{sub {ital t{anti t}}} = 7.5 {sup +1.9}{sub -1.6}{ital pb}. We report also on the observation of {ital t{anti t}} production in all of the hadronic decay channels using kinematic selection and {ital 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 {ital tb}}{vert_bar} = 1.12 {+-} 0.12.
