| Abstract: The $t\bar{t}$ production cross section ($\sigma_{t\bar{t}}$) is measured in proton-proton collisions at $\sqrt{s}$ = 7 TeV in data collected by the CMS experiment, corresponding to an integrated luminosity of 2.3 inverse femtobarns. The measurement is performed in events with two leptons (electrons or muons) in the final state, at least two jets identified as jets originating from b quarks, and the presence of an imbalance in transverse momentum. The measured value of $\sigma_{t\bar{t}}$ for a top-quark mass of 172.5 GeV is 161.9$\pm$ 2.5(stat.)$^{+5.1}_{-5.0}$(syst.)$\pm$ 3.6(lumi.) pb, consistent with the prediction of the standard model. | ||
