Complex-momentum form factors from lattice QCD

Maxwell T. Hansen, Gurtej Kanwar

We demonstrate that form factors evaluated with momenta analytically continued into the complex plane can be accessed directly from position-space Euclidean correlators such as tho…

$D \to (K π)_{27}$ at the SU(3)-flavour-symmetric point I: Methodology and strong phase determination

Matthew Black, Felix Erben, Maxwell T. Hansen +5

We present part one of an SU(3)-flavour-symmetric lattice QCD calculation of the amplitude for a $D$ -meson decaying to a $K π$ final state in the 27-dimensional irreducible represen…

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 $B_{c} \to ℓ ν_{ℓ} γ$ . We carry out our analysis on a…

$K π$ 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…

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…

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

Peter Boyle, Felix Erben, Vera Gülpers +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…

Peter Boyle, Felix Erben, Vera Gülpers +5

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