Abstract

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