Top Dilepton Cross Section Measurement Using the Tight Lepton+Isolated Track Sample

We present a top pair production cross section measurement in the dilepton channel using 750$ pb^{-1}$ of Run II data. We select events with one well- identified lepton, an isolated track, and a significant amount of missing transverse energy. The expected and observed numbers of events with 0 and 1 jets, where background is the dominant contribution, agree well. We measure the top dilepton cross section for events with 2 or more jets and show the kinematic distributions of the signal sample compared to the Standard Model expectation.
