On the Generalized Harmonic Polylogarithms of One Complex Variable
arXiv:1007.1891 · doi:10.1016/j.cpc.2011.02.011
Abstract
We describe how to compute numerically in the complex plain a set of Generalized Harmonic Polylogarithms (GHPLs) with square roots in the weights, using the C++/GiNaC numerical routines of Vollinga and Weinzierl. As an example, we provide the numerical values of the NLO electroweak light-fermion corrections to the Higgs boson production in gluon fusion in the case of complex W and Z masses.
