Recent Efforts in the Computation of String Couplings: [PDF]

, 1992
We review recent advances towards the computation of string couplings. Duality symmetry, mirror symmetry, Picard-Fuchs equations, etc. are some of the tools.Comment: Talk hold at the `International Conference on Modern Problems in Quantum Field Theorie,

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

Journal 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.

Hadronic vacuum polarization: three-pion channel [PDF]

EPJ Web of Conferences, 2020
The 3π-channel contribution to hadronic vacuum polarization (HVP) in the anomalous magnetic moment of the muon (g−2)µ is examined based on a dispersive representation of the γ* → 3π amplitude.

Dispersion relation for hadronic light-by-light scattering: pion pole

Journal of High Energy Physics, 2018
The pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon (g − 2) μ is fully determined by the doubly-virtual pion transition form factor. Although this crucial input quantity is, in principle, directly

C and CP violation in effective field theories

Journal of High Energy Physics, 2023
The quest for new sources of the simultaneous violation of C and CP symmetry was popular in the 1960s and has since been mostly neglected for more than half a century.

Three-body resonances in the φ 4 theory

Journal of High Energy Physics, 2023
We study the properties of three-body resonances using a lattice complex scalar φ 4 theory with two scalars, with parameters chosen such that one heavy particle can decay into three light ones.

Resonance form factors from finite-volume correlation functions with the external field method

Journal of High Energy Physics, 2022
A novel method for the extraction of form factors of unstable particles on the lattice is proposed. The approach is based on the study of two-particle scattering in a static, spatially periodic external field by using a generalization of the Lüscher ...

Selbstassemblierte (Aza‐)BODIPY Farbstoffe für Biomedizinische In Vivo Bildgebung

Angewandte Chemie, EarlyView.
Dieses Minireview klassifiziert (Aza‐)BODIPY‐Farbstoffe anhand ihrer molekularen Stapelungsmodi und Aggregattypen (H‐, oblique‐ oder J‐Typ) in wässrigen Medien und setzt diese Merkmale in Beziehung zu ihrer multimodalen Bildgebungsleistung. Durch die Verknüpfung von molekularem Design, Exzitonenkopplung und pfadabhängiger Assemblierung stellen wir ...
