• A bstractThe $\mathrm{t}\overline{\mathrm{t}}$ production cross section $\left( {{\sigma_{{\mathrm{t}\overline{\mathrm{t}}}}}} \right)$ 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 fb−1. 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… CONTINUE READING
