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

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

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

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…

$QED_{r}$ : 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…
