29 Jul 2004 | | Journal: | JHEP 0409 (2004) 042 | | Subject: | hep-ph | | Affiliation: | Durham, IPPP | | Abstract: | We compute the master integrals for massless two-loop vertex graphs with three off-shell legs. These master integrals are relevant for the QCD corrections to H to V*V* (where V = W, Z) and for two-loop studies of the triple gluon (and quark-gluon) vertex. We employ the differential equation technique to provide series expansions in epsilon for the various master integrals. The results are analytic and contain a new class of two-dimensional harmonic polylogarithms. | | Source: | arXiv, hep-ph/0407343 | | Services: | Forum | Review | PDF | Favorites | |
