Title: Measurement of the top-antitop quark pair differential cross section with respect to the invariant mass of the pair in proton-antiproton collisions at a center of mass energy of 1.96 TeV

Abstract

I present a measurement of the t$$\bar{t}$$ differential cross section, dσ/dMt$$\bar{t}$$, in p$$\bar{p}$$ collisions at √s = 1.96 TeV using 2.7 fb-1 of CDF II data. I find that dσ/dMt$$\bar{t}$$ is consistent with the Standard Model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions. I set limits on the ratio Κ/MPl in the Randall-Sundrum model by looking for Kaluza Klein gravitons which decay to top quarks. I find Κ/MPl > 0.16 at the 95% confidence level.
