Abstract
 The first measurement of the cross section for top-quark pair production in pp collisions at the Large Hadron Collider at center-of-mass energy View the MathML source has been performed using a data sample corresponding to an integrated luminosity of 3.1±0.3 pb−1 recorded by the CMS detector. This result utilizes the final state with two isolated, highly energetic charged leptons, large missing transverse energy, and two or more jets. Backgrounds from DrellYan and non-W/Z boson production are estimated from data. Eleven events are observed in the data with 2.1±1.0 events expected from background. The measured cross section is 194±72(stat.)±24(syst.)±21(lumi.) pb, consistent with next-to-leading order predictions.
