Open AccessMuon-electron scattering at NNLO
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 correctio...

Open AccessErratum to: Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution
In the course of working on the extension [2] of ref. [1] to Higgsino dark matter annihilation, we became aware of two mistakes and a number of typos in this article.

Open AccessResummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution
The annihilation cross section of weakly interacting TeV scale dark matter particles χ0 into photons is affected by large quantum corrections due to electroweak Sudakov logarithms and the Sommerfeld effect. We ex...

Open AccessTo \({d}\) , or not to \({d}\) : recent developments and comparisons of regularization schemes
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 si...

Open AccessSCET approach to regularization-scheme dependence of QCD amplitudes
We investigate the regularization-scheme dependence of scattering amplitudes in massless QCD and find that the four-dimensional helicity scheme (FDH) and dimensional reduction (DRED) are consistent at least up...

Open AccessRenormalization-group improved fully differential cross sections for top pair production
We extend approximate next-to-next-to-leading order results for top-pair production to include the semi-leptonic decays of top quarks in the narrow-width approximation. The new hard-scattering kernels are impl...
