Improved Standard-Model predictions for $η^{(')} \to ℓ^{+} ℓ^{-}$

Noah Messerli, Martin Hoferichter, Bai-Long Hoid +2

The rare decays $η^{(')} \to ℓ^{+} ℓ^{-}$ , $ℓ \in {e, μ}$ , are highly suppressed in the Standard Model, both by their chirality structure and the required loop attaching the…

Radiative corrections to $τ \to π π ν_{τ}$

Gilberto Colangelo, Martina Cottini, Martin Hoferichter +1

Hadronic $τ$ decays present an opportunity to determine the isovector part of the hadronic-vacuum-polarization contribution to the anomalous magnetic moment of the muon in a way co…

Improved calculation of radiative corrections to $τ \to π π ν_{τ}$ decays

Gilberto Colangelo, Martina Cottini, Martin Hoferichter +1

A reliable calculation of radiative corrections to $τ \to π π ν_{τ}$ decays is an important prerequisite for using hadronic $τ$ decays for a data-driven evaluation of the hadronic-vacuum…

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, $a_{μ}$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…

Dispersion relation for hadronic light-by-light scattering: $η$ and $η^{'}$ poles

Simon Holz, Martin Hoferichter, Bai-Long Hoid +1

The pseudoscalar-pole contributions to hadronic light-by-light scattering are determined by the respective transition form factors (TFFs) into two virtual photons. These TFFs const…

Precision evaluation of the $η$ - and $η^{'}$ -pole contributions to hadronic light-by-light scattering in the anomalous magnetic moment of the muon

Simon Holz, Martin Hoferichter, Bai-Long Hoid +1

Next to the $π^{0}$ pole, $η$ and $η^{'}$ intermediate states give rise to the leading singularities of the hadronic light-by-light tensor, resulting in sizable contributions to the ano…

Prospects for precise predictions of $a_{μ}$ in the Standard Model

G. Colangelo, M. Davier, A. X. El-Khadra +79

We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon $g - 2$ Theory Initiative to…

A dispersive analysis of $η^{'} \to π^{+} π^{-} γ$ and $η^{'} \to ℓ^{+} ℓ^{-} γ$

Simon Holz, Christoph Hanhart, Martin Hoferichter +1

We present a dispersive representation of the $η^{'}$ transition form factor that allows one to account, in a consistent way, for the effects of $ρ$ - $ω$ mixing in both the isoscalar a…
