Abstract 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 contributions. All fermionic corrections as well as the photonic subse

Abstract We present two novel results about the universal structure of radiative QED amplitudes in the soft and in the collinear limit. On the one hand, we extend the well-known Low-Burnett-Kroll theorem to the one-loop level and give the explicit re

Abstract In this manuscript, we report the outcome of the topical workshop: paving the way to alternative NNLO strategies ( https://indico.ific.uv.es/e/WorkStop-ThinkStart_3.0 ), by presenting a discussion about different frameworks to perform precis

Abstract We present an extension of the FKS subtraction scheme beyond next-to-leading order to deal with soft singularities in fully differential calculations within QED with mas- sive fermions. After a detailed discussion of the next-to-next-to-lead

Abstract We present the heavy-to-light form factors with two different non-vanishing masses at next-to-next-to-leading order and study its expansion in the small mass. The leading term of this small-mass expansion leads to a factorized expression for

We present a general purpose Monte Carlo program for the calculation of the radiative muon decay μ→eνν¯γ and the radiative decays τ→eνν¯γ and τ→μνν¯γ at next-to-leading order in the Fermi theory. The full dependence on the lepto

Abstract We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Comparing the computation of simple quantities in the various s

Using the automation program GoSam, fully differential NLO corrections were obtained for the rare decay of the muon μ→eνν¯ee. This process is an important Standard Model background to searches of the Mu3e Collaboration for lepton-flavor violati
