Muon-electron scattering at NNLO
A. Broggio, T. Engel, A. Ferroglia +8
We present the first calculation of the complete set of NNLO QED corrections for muon-electron scattering. This includes leptonic, non-perturbative hadronic, and photonic contribut…
Towards two-loop automation in OpenLoops
Stefano Pozzorini, Natalie Schär, Max F. Zoller
NLO scattering amplitudes are provided by fully automated numerical tools, such as OpenLoops, for a very wide range of processes. In order to match the numerical precision of curre…
Two-loop amplitude generation in OpenLoops
Stefano Pozzorini, Natalie Schär, Max F. Zoller
Numerical tools, such as OpenLoops, provide NLO scattering amplitudes for a very wide range of hard scattering amplitudes in a fully automated way. In order to match the numerical…
Two-loop tensor integral coefficients in OpenLoops
Stefano Pozzorini, Natalie Schär, Max F. Zoller
We present a new and fully general algorithm for the automated construction of the integrands of two-loop scattering amplitudes. This is achieved through a generalisation of the op…
