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…

Exploratory calculation of the rare hyperon decay $I^£^{+} \to p ℓ^{+} ℓ^{-}$ from lattice QCD

Felix Erben, Vera GÃ¼lpers, Maxwell T. Hansen +2

The rare hyperon decay $I^£^{+} \to p ℓ^{+} ℓ^{-}$ is a flavour-changing neutral current process mediated by an $s \to d$ transition that occurs only at loop level within the Standa…

Light and strange vector resonances from lattice QCD at physical quark masses

Peter Boyle, Felix Erben, Vera GÃ¼lpers +5

We present the first ab initio calculation at physical quark masses of scattering amplitudes describing the lightest pseudoscalar mesons interacting via the strong force in the vec…

Physical-mass calculation of $I ¨ (770)$ and $K^{*} (892)$ resonance parameters via $I ¨ I ¨ $ and $K I ¨ $ scattering amplitudes from lattice QCD

Peter Boyle, Felix Erben, Vera GÃ¼lpers +5

We present our study of the $I ¨ (770)$ and $K^{*} (892)$ resonances from lattice quantum chromodynamics (QCD) employing domain-wall fermions at physical quark masses. We determine the…
