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

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

The rare decays $I^\cdot^{(')} \to ℓ^{+} ℓ^{-}$ , $ℓ \in {e, I^¼}$ , are highly suppressed in the Standard Model, both by their chirality structure and the required loop attaching th…

Improved calculation of radiative corrections to $I ¨ \to I ¨ I ¨ I^½_{I ¨} $ decays

Gilberto Colangelo, Martina Cottini, Martin Hoferichter +1

A reliable calculation of radiative corrections to $I ¨ \to I ¨ I ¨ I^½_{I ¨} $ decays is an important prerequisite for using hadronic $I ¨ $ decays for a data-driven evaluation of the hadronic-…

Radiative corrections to $I ¨ \to I ¨ I ¨ I^½_{I ¨} $

Gilberto Colangelo, Martina Cottini, Martin Hoferichter +1

Hadronic $I ¨ $ 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 c…

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, $a_{I^} ¼$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

Dispersion relation for hadronic light-by-light scattering: $I^\cdot$ and $I^\cdot^{'}$ 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 $I^\cdot$ - and $I^\cdot^{'}$ -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 $I ¨ ^{0}$ pole, $I^\cdot$ and $I^\cdot^{'}$ intermediate states give rise to the leading singularities of the hadronic light-by-light tensor, resulting in sizable contributions to the…
