Anerkennung in den Wissenschaften sichtbar machen: Wie die Bibliometrie durch die soziale Netzwerkanalyse neue Impulse erhält

open access: yesÖsterreichische Zeitschrift für Geschichtswissenschaften, 2012
The article intends to show how a way of combining methods of social network analysis with methods of classical bibliometry meaningfully may be applied within historical studies.

Dispersive analysis of the Primakoff reaction $$\gamma K \rightarrow K \pi $$ γ K → K π

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We provide a dispersion-theoretical representation of the reaction amplitudes $$\gamma K\rightarrow K \pi $$ γ K → K π in all charge channels, based on modern pion–kaon P-wave phase shift input.

Quark-mass dependence in $$\omega \rightarrow 3\pi $$ ω→3π decays

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study the quark-mass dependence of $$\omega \rightarrow 3\pi $$ ω→3π decays, based on a dispersion-theoretical framework. We rely on the quark-mass-dependent scattering phase shift for the pion–pion P-wave extracted from unitarized chiral perturbation

Functional renormalization group study of the Anderson–Holstein model

open access: yesNew Journal of Physics, 2014
We present a comprehensive study of the spectral and transport properties in the Anderson–Holstein model both in and out of equilibrium using the functional renormalization group (fRG).

Analysis of rescattering effects in $$3\pi $$ 3 π final states

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Decays into three particles are often described in terms of two-body resonances and a non-interacting spectator particle. To go beyond this simplest isobar model, crossed-channel rescattering effects need to be accounted for.

Particle-dimer approach for the Roper resonance in a finite volume

open access: yesJournal of High Energy Physics, 2023
We propose a new finite-volume approach which implements two- and three-body dynamics in a transparent way based on an Effective Field Theory Lagrangian.

A Theory for Game Theories

open access: yes, 2007
Game semantics is a valuable source of fully abstract models of programming languages or proof theories based on categories of so-called games and strategies. However, there are many variants of this technique, whose interrelationships largely remain to be elucidated. This raises the question: what is a category of games and strategies?

Diskurs als konstituierende Grundlage der Medienpädagogik und Folgerungen aus systemtheoretischer Sicht

open access: yesMedienPädagogik: Zeitschrift für Theorie und Praxis der Medienbildung, 2017
Medienpädagogik lässt sich beschreiben als Wissenschaft und Lehre von medienbezogenen erziehungs- und bildungsrelevanten Aktivitäten und ihren Voraussetzungen und Bedingungen. Vielfältige Entwürfe und Diskussionslinien in der Medienpädagogik haben bisher

Patterns of C- and CP-violation in hadronic η and η′ three-body decays

open access: yesJournal of High Energy Physics, 2022
We construct hadronic amplitudes for the three-body decays η (′) → π + π − π 0 and η′ → ηπ + π − in a non-perturbative fashion, allowing for C- and CP-violating asymmetries in the π + π − distributions.
