Abstract (data abstract)
CERN-LHC. Measurement of the cross section for the production of top quark pairs in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample has a total integrated luminosity of 3.1 +- 0.3 pb-1 with 2.1 +- 1.0 events being observed above the expected background.
