Dispersive analysis of the process
Bai-Long Hoid, Igor Danilkin, Anna Testa +1
We present a dispersive amplitude analysis of the low-energy system in the radiative decay , using the mass-independent BESIII and i…
Improved Standard-Model predictions for
Noah Messerli, Martin Hoferichter, Bai-Long Hoid +2
The rare decays , , are highly suppressed in the Standard Model, both by their chirality structure and the required loop attaching th…
Dispersive analysis of the process
Bai-Long Hoid, Igor Danilkin, Marc Vanderhaeghen
We present an analysis of the radiative decay in a dispersive framework, where the two-pion subsystem undergoes strong final-state interactions that cover 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…
Modified Lüscher zeta-function and the modified effective range expansion in the presence of a long-range force
Rishabh Bubna, Hans-Werner Hammer, Bai-Long Hoid +3
An efficient numerical algoritm is proposed for the calculation of the modified Lüscher zeta-function in the presence of a long-range force. Using the formalism developed in Ref.~…
Extracting the chiral anomaly from
Martin Hoferichter, Bai-Long Hoid, Bastian Kubis
The strength of the interaction of three pions and a photon, is predicted by the axial anomaly in terms of the pion decay constant, a relation that is frequently used to…
