I present the next-to-next-to-leading-logarithm (NNLL) resummation of soft and collinear gluon corrections to single top quark production in the s channel. Attaining NNLL accuracy involves the calculation of the two-loop soft anomalous dimension for the partonic subprocesses. Finite-order expansions of the resummed cross section are calculated through next-to-next-to-leading order. Numerical results are presented for s-channel single top quark production at the Tevatron and the LHC, including the dependence of the cross sections on the top quark mass and the uncertainties in the theoretical prediction. The higher-order corrections are significant for energies at both colliders and they decrease the theoretical uncertainty.

- NNLL threshold resummation for top-pair and single-top production (2012, result): “Our theoretical results for the Tevatron can be found in [10,12] and they are in good agreement with the recent Tevatron data; the total cross section that we ˇnd for the sum of t plus s channels is 3.”
- Evidence for the Higgs-boson Yukawa coupling to tau leptons with the ATLAS detector (2015, positive): “The overall normalisation of the ggF process is taken from a calculation at next-to-next-to-leading-order (NNLO) [48– 53] in QCD, including soft-gluon resummation up to next-to-next-to-leading logarithm terms (NNLL) [54].”
