Selection of Top-like events in pp collisions at sqrt(s) = 7 TeV in early CMS data

Studies are presented of the selection of events consistent with top quark pair production in data recorded by the CMS detector at the LHC, corresponding to an integrated luminosity of 0.84 pb$^{-1}$ and a center-of-mass energy $\sqrt{s}$ = 7 TeV. Results are presented for the lepton+jets and dilept...

description Studies are presented of the selection of events consistent with top quark pair production in data recorded by the CMS detector at the LHC, corresponding to an integrated luminosity of 0.84 pb$^{-1}$ and a center-of-mass energy $\sqrt{s}$ = 7 TeV. Results are presented for the lepton+jets and dilepton channels. Events yields in data are compared to those in simulation and several background processes are estimated using data-driven techniques. The observed yields of top-antitop candidate events are roughly consistent with the Standard Model.
