Abstract

We present studies of the selection of events consistent with top quark pair production
in the first 78 nb?1 of pp collisions at sqrt(s) = 7 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.
