Top Quark Pair Production beyond the Next-to-Leading Order.

Valentin Ahrens, Andrea Ferroglia, Matthias Neubert, Ben D. Pecjak & Li Lin Yang
We report on recent calculations of the total cross section and differential distributions of top quark pair production at hardon colliders, including the invariant mass distribution, the transverse momentum and rapidity distributions, as well as the forward-backward asymmetry. The calculations are based on soft gluon resummation at the next-to-next-to-leading logarithmic accuracy.
