Description
We present two searches involving final states with top quarks or with
topologies similar to those observed in top quark decays. The first is a search
for the pair production of a fourth generation $t'$ quark and its antiparticle,
followed by their decay to a W boson and a jet, based on an integrated
luminosity of 5.3 fb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV.
The second is a search for the production of a heavy gauge boson $W'$, that decays
to third generation quarks. In both cases we set 95\% C.L.~upper limits on the
production cross sections and translate these into limits on the mass of
the fourth generation quarks oir of the $W'$ boson in a variety of models.
