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