Abstract
I present a measurement of the tt differential cross section, do-/dM, in pp collisions at Vi 1.96
TeV using 2.7 fb-1 of CDF II data. I find that do/dMg is consistent with the Standard Model
expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions. I set limits on the
ratio n/Mp, in the Randall-Sundrum model by looking for Kaluza Klein gravitons which decay to
top quarks. I find n/Mp, > 0.16 at the 95% confidence level.ii
