Abstract
We present a measurement of the tt&#773; differential cross section with respect to the tt&#773; invariant mass, dσ/dMtt&#773; , in pp&#773; collisions at √s=1.96  TeV using an integrated luminosity of 2.7  fb-1 collected by the CDF II experiment. The tt&#773; invariant mass spectrum is sensitive to a variety of exotic particles decaying into tt&#773; pairs. The result is consistent with the standard model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions.
