Numerical scattering amplitudes with pySecDec [PDF]
Computer Physics Communications, 2023 We present a major update of the program pySecDec, a toolbox for the evaluation of dimensionally regulated parameter integrals. The new version enables the evaluation of multi-loop integrals as well as amplitudes in a highly distributed and flexible way, optionally on GPUs. The program has been optimised and runs up to an order of magnitude faster than

A Monte Carlo approach to the 4D scattering equations
Journal of High Energy Physics, 2018 The scattering equation formalism is a general framework for calculation of amplitudes in theories of massless particles. We provide a detailed introduction to the 4D scattering equation framework accessible to non-experts, outline current difficulties ...

Projectivity of planar zeros in field and string theory amplitudes
Journal of High Energy Physics, 2017 We study the projective properties of planar zeros of tree-level scattering amplitudes in various theories. Whereas for pure scalar field theories we find that the planar zeros of the five-point amplitude do not enjoy projective invariance, coupling ...
