2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/129082I 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.6 pages, 3 figures, presented at DIS 2007, Munich, Germany, April 16-20, 2007High Energy Physics - Phenomenologytext
