NGluon: A package to calculate one-loop multi-gluon amplitudes

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present a computer library for the numerical evaluation of colour-ordered n-gluon amplitudes at one-loop order in pure Yang–Mills theory. The library uses the recently developed technique of generalised unitarity. Running in double precision the library yields reliable results for up to 14 gluons with only a small fraction of events requiring a re-evaluation using extended floating point arithmetic. We believe that the library presented here provides an important contribution to future LHC...
