Double-real corrections to color singlet decay in a parton-shower inspired scheme
John M. Campbell, Stefan Höche, Stefan Höche +1
We introduce a local infrared subtraction method for next-to-next-to-leading order QCD calculations in color singlet decays, which is modeled on the evolution algorithm of a parton…

QCD splitting functions beyond kinematical limits
John M. Campbell, Stefan Höche, Max Knobbe +2
We present a systematic decomposition of QCD splitting functions into scalar dipole radiators and pure splitting remainders up to second order in the strong coupling. The individua…

Algorithms for numerically stable scattering amplitudes
Enrico Bothmann, John M. Campbell, Stefan Höche +1
The numerically stable evaluation of scattering matrix elements near the infrared limit of gauge theories is of great importance for the success of collider physics experiments. We…
