Multi-gluon one-loop amplitudes numerically
نویسنده
چکیده
A c++ implementation of the Ds-dimensional unitarity cut algorithm for the numerical evaluation of the virtual contribution to NLO QCD amplitudes is presented. The current version includes an arbitrary number of external gluons with gluonic propagators in the loop. The building blocks are tree level color-ordered amplitudes with gluons and with gluons and two scalars in five dimensions. Numerical stability issues are addressed and agreement has been reached with the results published in the literature.

Multi-gluon one-loop amplitudes using tensor integrals1
An efficient numerical algorithm to evaluate one-loop amplitudes using tensor integrals is presented. In particular, it is shown by explicit calculations that for ordered QCD amplitudes with a number of external legs up to 10, its performance is competitive with other methods.
متن کاملOn planar gluon amplitudes/Wilson loops duality
There is growing evidence that on-shell gluon scattering amplitudes in planar N = 4 SYM theory are equivalent to Wilson loops evaluated over contours consisting of straight, light-like segments defined by the momenta of the external gluons. This equivalence was first suggested at strong coupling using the AdS/CFT correspondence and has since been verified at weak coupling to one loop in perturb...
متن کاملBootstrapping Multi-Parton Loop Amplitudes in QCD
We present a new method for computing complete one-loop amplitudes, including their rational parts, in non-supersymmetric gauge theory. This method merges the unitarity method with onshell recursion relations. It systematizes a unitarity-factorization bootstrap approach previously applied by the authors to the one-loop amplitudes required for next-to-leading order QCD corrections to the process...

This note reports on an independent implementation of calculating one-loop amplitudes semi-numerically using generalized unitarity techniques. The algorithm implemented in form of a C++ code closely follows the method by Ellis, Giele, Kunszt and Melnikov [1, 2]. For the case of gluons, the algorithm is briefly reviewed. Double-precision results are presented documenting the accuracy and efficie...
متن کاملApproximate Universality of N = 4 Super-Yang–Mills One-Loop Amplitudes
A study of the colour-ordered one-loop amplitudes in N = 4 SYM reveals a surprising property: numerically, the amplitudes have an Approximately Universal form A 1-loop n ∼ Atree n × Un, where Un is helicity independent. This form is exact if the amplitude is a MHV amplitude, but has an “error” which is typically less than 1% for the six, seven and eight gluon NMHV one-loop amplitudes. 1 Approxi...
