How to determine the branch points of correlation functions in Euclidean space II: Three-point functions

Autor: Huber, Markus Q., Kern, Wolfgang J., Alkofer, Reinhard

The analytic structure of elementary correlation functions of a quantum field is relevant for the calculation of masses of bound states and their time-like properties in general. In quantum chromodynamics, the calculation of correlation functions for

The analytic structure of three-point functions from contour deformations

Autor: Huber, Markus Q., Kern, Wolfgang J., Alkofer, Reinhard

Publikováno v: Phys. Rev. D 107 (2023) 074026

We explore the analytic structure of three-point functions using contour deformations. This method allows continuing calculations analytically from the spacelike to the timelike regime. We first elucidate the case of two-point functions with explicit

Accelerometry-based classification of circulatory states during out-of-hospital cardiac arrest

Autor: Kern, Wolfgang J., Orlob, Simon, Bohn, Andreas, Toller, Wolfgang, Wnent, Jan, Gräsner, Jan-Thorsten, Holler, Martin

Objective: Exploit accelerometry data for an automatic, reliable, and prompt detection of spontaneous circulation during cardiac arrest, as this is both vital for patient survival and practically challenging. Methods: We developed a machine learning
