We present a search for t over(t, ) events with a tau lepton in the final state. The data sample corresponds to an integrated luminosity of 194 pb-1 collected with the CDF II detector from p over(p, ) collisions at a center of mass energy of 1.96 TeV. We observe two events with an expected signal of 1.0 0.2 events and a background of 1.3 0.3 events. We determine a 95% confidence level upper limit on r, the ratio of the measured rate of t q to the expectation, of 5.2. 2006 Elsevier B.V. All rights reserved.
