I show that the corrections provide significant enhancements to the cross sections in both cases. For single top production the soft gluon corrections dominate the cross section, particularly in the s channel and in tW production. For Higgs production it is shown that purely collinear terms have to be included as well to provide an accurate calculation.14 pages, 9 figures; presented at Cracow Epiphany Conference on LHC Physics, January 2008High Energy Physics - Phenomenologytext
