Real radiative decays of heavy pseudoscalar mesons

Teseo San Jose, Yasumichi Aoki, Matteo Di Carlo +9

We report our ongoing lattice QCD study of radiative leptonic decays of the charged pseudoscalar mesons $D$ , $D_{s}$ , $B$ , and $B_{c} \to ℓ I^½_{ℓ} I^^{3}$ . We carry out our analysis on…

$K I ¨ $ scattering as a step towards $B \to K^{*} ℓ^{+} ℓ^{-}$ from Lattice QCD

Felix Erben, Matthew Black, Peter Boyle +7

Rare $b \to s ℓ^{+} ℓ^{-}$ decays provide some of the most sensitive tests of the Standard Model and require precise and systematically improvable hadronic input from lattice QCD. F…

$QED_{r}$ : a finite-volume QED action with redistributed spatial zero-momentum modes

Matteo Di Carlo, Maxwell T. Hansen, Nils Hermansson-Truedsson +1

We present a finite-volume QED action designed to improve the infinite-volume extrapolation of hadronic observables in precision lattice QCD+QED calculations. The action proposed i…

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…

Long distance contributions to neutral $D$ -meson mixing from lattice QCD

Matteo Di Carlo, Felix Erben, Maxwell T. Hansen

The study of neutral $D$ -meson mixing provides a unique probe of long-distance effects in the charm sector, where Standard Model contributions are dominated by nonperturbative effe…

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…
