Abstract
We present a measurement of the differential cross section with respect to the invariant mass, , in collisions at using an integrated luminosity of collected by the CDF II experiment. The invariant mass spectrum is sensitive to a variety of exotic particles decaying into pairs. The result is consistent with the standard model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions.
