A dispersive method to study CP asymmetries in hadronic multi-body decays
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +5
We present the details of a dispersive method to construct the amplitudes for hadronic multibody decays based on the universality of pairwise hadronic final-state interactions…
Understanding large localized CP violation in using dispersive methods
L. A. Heuser, A. Reyes-Torrecilla, C. Hanhart +4
We utilize the universality of pion-pion () final-state interactions at small invariant masses to understand the enhanced localized CP violation in ,…
Dispersive Analysis of - and -Meson Form Factors with Chiral and Heavy-Quark Constraints
Simon Mutke, Leon A. Heuser, Ingrid Dax +2
We analyze the isovector vector form factors of , , , and mesons at low energies. We employ all constraints due to chiral and heavy-quark symmetry, and include the…
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…
From pole parameters to line shapes and branching ratios
L. A. Heuser, G. Chanturia, F. -K. Guo +3
Resonances are uniquely characterized by their complex pole locations and the corresponding residues. In practice, however, resonances are typically identified experimentally as st…
