Numerical Evaluation of one-loop QCD amplitudes — Simon Badger2, •Benedikt Biedermann1, and Peter Uwer1 — 1Humboldt-Universität zu Berlin, — 2The Niels Bohr Insitute, Copenhagen, Denmark
We present the publicly available program NGluon allowing the numerical evaluation of one-loop primitve amplitudes in massless QCD. So far, the program was restricted to the pure gluonic case with an arbitrary number of external legs. The focus of this talk is the extension to one-loop amplitudes including an arbitrary number of massless quark pairs. We discuss in detail the algorithmic differences to the pure gluonic case and present cross checks to validate our implementation. The numerical accuracy is investigated in detail and first phenomenological studies are shown.
