A Fully Numerical Approach to One-Loop Amplitudes
We suggest a new approach for the automatic and fully numerical evaluation of oneloop scattering amplitudes in perturbative quantum field theory. We use suitably formulated dispersion relations to perform the calculation as a convolution of treelevel amplitudes. This allows to take advantage of the iterative numerical algorithms for the evaluation of leading order matrix elements. Preprint subm...
متن کاملNumerical evaluation of one-loop QCD amplitudes
We present the implementation of the numerical generalized unitarity algorithm in the public code NJET. As phenomenological applications we discuss three and four jet production at the LHC to next-to-leading order accuracy in massless QCD.
متن کاملAn algebraic/numerical formalism for one-loop multi-leg amplitudes
We present a formalism for the calculation of multi-particle one-loop amplitudes, valid for an arbitrary number N of external legs, and for massive as well as massless particles. A new method for the tensor reduction is suggested which naturally isolates infrared divergences by construction. We prove that for N ≥ 5, higher dimensional integrals can be avoided. We derive many useful relations wh...
متن کاملOne-loop corrections to five-gluon amplitudes.
We present the one-loop helicity amplitudes with five external gluons. The computation employs string-based methods, new techniques for performing tensor integrals, and improvements in the spinor helicity method.

متن کاملOne loop multiphoton helicity amplitudes.
We use the solutions to the recursion relations for double-off-shell fermion currents to compute helicity amplitudes for n-photon scattering and electronpositron annihilation to photons in the massless limit of QED. The form of these solutions is simple enough to allow all of the integrations to be performed explicitly. For n-photon scattering, we find that unless n = 4, the amplitudes for the ...
