Selection of Top-Like Events in the Dilepton and Lepton-plus-Jets Channels in Early 7 TeV Data

We present studies of the selection of events consistent with top quark pair production in the first 78~$\rm nb^{-1}$ of pp collisions at $\sqrt{s}= 7 \rm\ TeV$ recorded by the CMS detector at the LHC. Results are presented for the lepton+jets and dilepton channels. In this initial small sample we d...

description We present studies of the selection of events consistent with top quark pair production in the first 78~$\rm nb^{-1}$ of pp collisions at $\sqrt{s}= 7 \rm\ TeV$ recorded by the CMS detector at the LHC. Results are presented for the lepton+jets and dilepton channels. In this initial small sample we do not expect a significant contribution from top-quark production; however, predicted background yields are compared to the overall yield of events collected in this early data. Kinematic comparisons demonstrate good agreement between simulated events and current data, putting the prospect of measurements of the top-quark pair-production cross section on firm ground.
