High-order corrections and subleading logarithms for top quark production

High-order corrections and subleading logarithms for top quark production

We derive high-order threshold corrections for top quark production in hadronic collisions from resummation calculations. We present analytical expressions for the cross section through next-to-next-to-next-to-next-to-leading order (N 4 LO) and next-to-next-to-leading logarithmic accuracy. Special attention is paid to the role of subleading logarithms and how they relate to the convergence of t...

Higher-order Threshold Corrections for Single Top Quark Production

I discuss single top quark production at the Tevatron and the LHC. The cross section, including soft-gluon threshold corrections through NNNLO, is presented for each partonic channel. The higher-order corrections provide significant contributions to the single top cross sections at both colliders.

Higher-order Corrections to Top-antitop Pair and Single Top Quark Production

The top quark plays an important role in the Standard Model of particle physics as the most massive elementary particle, relevant to electroweak physics. The top was discovered via pair production [1, 2] and has also been more recently produced via single top [3, 4] channels at the Tevatron. On the theoretical side, QCD corrections are significant for top quark production and even higherorder c...
