Description
We present the publicly available program NGLUON allowing the
numerical evaluation of colour-ordered amplitudes at one-loop
order in massless QCD.
The program allows the evaluation of one-loop amplitudes
for an arbitrary number of gluons. We discuss in detail the speed as
well as the numerical stability. In addition the packages allows the
evaluation of one-loop scattering amplitudes using extended floating
point precision.
Furthermore we discuss the extension to one-loop amplitudes including massless
quarks and show some phenomenological applications.
