2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/164139We discuss the recent derivation of the two loop virtual QCD corrections to the W boson pair production in the quark-anti-quark-annihilation channel in the limit where all kinematical invariants are large compared to the mass of the W boson. In particular, we describe the use of the PSLQ algorithm on an example integral.Presented at DIS2008: 16th International Workshop on Deep-Inelastic Scattering and Related Subjects, 7-11 April 2008, University College London, UK, 4 pages, 1 figureHigh Energy Physics - Phenomenologytext
