Top Quark Pair Production Cross Section and Forward-Backward Asymmetry at the Tevatron

Understand

We present recent results on top quark pair production cross section and forward-backward asymmetry at the Tevatron.

• Three new cross section measurements from CDF and one new measurement from DO are presented that utilize the full dataset available.
• A new DO top cross section combination gives a ttbar production cross section of sigma_ttbar = 7.83 + 0.46-0.45 (stat) + 0.64-0.53 (syst) +-0.48 (lumi).
• The new CDF cross section combination for ttbar production is found to be 7.0 +- 0.3 (stat) +- 0.4 (syst) +- 0.4 (lumi) pb giving a total uncertainty of 9%, very close to the that of the current best theoretical predictions.
