520 $a We thus conclude that the top mean lifetime is less than 145 fs (175 fs) at 90% (95%) C.L.
520 $a This dissertation presents the first direct limit on the t quark lifetime, measured in tt¯ pair production candidate events from a 318 pb-1 sample of p + p¯ collisions recorded by the Collider Detector at Fermilab (CDF). Candidate events are identified by a leptonically decaying W+/- boson and three or more jets, at least one of which contains a secondary vertex. In each event we measure the transverse track-to-beam displacement (impact parameter) of the lepton from the W+/- decay, and compare the distribution to templates constructed from tt¯ event simulations with a variable t lifetime. Anticipated background distributions are measured with a combination of Monte Carlo event simulation and control samples, and included in the templates.
