Book excerpt: We present the results of a search for pair production of a heavy top-like (t') quark decaying to Wq final states using data corresponding to an integrated luminosity of 5.6 fb−1 collected by the CDF II detector in proton-antiproton collisions at [square root s] = 1.96 TeV center of mass energy. A searche for t' --> Wb in events containing a lepton and four or more jets is conducted. By performing a fit to the two-dimensional distribution of total transverse energy versus reconstructed t' quark mass, we set upper limits on the t't̄' pair production cross section and exclude a standard model fourth-generation t' quark decaying to Wb with mass below 358 GeV/c2 at 95% CL.
