Abstract
We present an optimization of the
reduction algorithm of one-loop amplitudes in terms of
master integrals. It is based on the exploitation
of the polynomial structure of the integrand
when evaluated at values of the loop-momentum
fulfilling multiple cut-conditions, as
emerged in the OPP-method.
The reconstruction of the polynomials,
needed for the complete reduction, is
rendered very versatile by using a projection-technique
based on the Discrete Fourier Transform.
The novel implementation is applied
in the context of the NLO QCD corrections to u
â W+WâW+.
