Abstract
\nMeasurements of the inclusive and differential cross section for the production of top quark pairs in proton-(anti)proton collision at center-of-mass energies of 1.96, 7.0 and 8.0 TeV are presented and compared with the latest theory predictions and Monte-Carlo models. In addition, first measurements of the production of top quark pairs in association with additional jets or with a boson are highlighted. All measurements are in good agreement with the Standard Model.\n

A program to calculate the total cross section for top-quark pair production in hadronic collisions takes into account recent theoretical developments and allows for studies of the theoretical uncertainty by separate variations of the factorization and renormalization scales.

This is the first ever next-to-next- to-leading order calculation of an observable with more than two colored partons and/or massive fermions at hadron colliders, and it is expected that once all subdominant partonic reactions are accounted for, the perturbative theoretical uncertainty for this observable could drop below ±2%.

The result is consistent with the standard model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions, and is sensitive to a variety of exotic particles decaying into tt[over ] pairs.

The tt cross section ratio is measured using two complementary methods, a b-jet tagging measurement and a topological approach, and a best linear unbiased estimate is used to combine both measurements.
