Computation of one-loop gluon amplitudes — •Benedikt Biedermann — Humboldt University of Berlin, Germany

A numerical approach for the computation of QCD one-loop gluon amplitudes in pure gauge theory is presented. Using generalized unitarity, we compute the coefficients of the occuring scalar one-loop integrals. As basic ingredient, the Berends-Giele recursion is used to construct on-shell tree amplitudes. The performance of the program is explored and the algorithms of the implemented methods are explained.
