Title:
Measurement of the ttbar Cross Section and Search for Anomalous
Semi-leptonic Decays at CDF
Abstract:
Ten years have passed since the top quark discovery and still very
little is known experimentally about the heaviest of the quarks. In
this talk, I will review the production and decay mechanisms of the
top quark, discuss the techniques used to identify b-jets from top
decays and report on the measurement of the top production cross
section. I will then follow up on the Run I CDF excess of jets in
W+jets events with both a secondary vertex and a semi-leptonic decay,
which indicated a possible anomalous rate of semi-leptonic decay from
heavy flavor hadrons.
