The impact of and $γ^* N$ interactions on our understanding of nucleon excitations
Volker Burkert, Gernot Eichmann, Eberhard Klempt
We review recent progress in our understanding of the nucleon excitation spectrum. Thanks to dedicated efforts at facilities such as ELSA, MAMI and Jefferson Lab, several new nucle…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…
Five-body systems with Bethe-Salpeter equations
Gernot Eichmann, M. T. Peña, Raul D. Torres
We extend the Bethe-Salpeter formalism to systems made of five valence particles. Restricting ourselves to two-body interactions, we derive the subtraction terms necessary to preve…
Five-point functions and the permutation group S5
Gernot Eichmann, Raul D. Torres
Five-point functions and five-body wave functions play an important role in many areas of nuclear and particle physics, e.g., in 2 -> 3 scattering processes, in the five-gluon vert…
