Contribution

It introduces the first complete NLO electroweak corrections combined with NNLO QCD for top-quark pair distributions at the Tevatron.

Findings

Predictions include all Standard Model corrections at NLO and NNLO levels.

Assessment of dynamical scale effects on Tevatron measurements.

Enhanced agreement with experimental data.

Abstract

We calculate all main top-quark pair differential distributions at the Tevatron. For the first time Tevatron predictions for this process include all Standard Model corrections through NLO (referred to as complete-NLO) consistently combined with previously computed NNLO QCD corrections. We also assess, for the first time, the impact of dynamical scales on predictions for the latest Tevatron measurements.
