Lattice Calculation of Short-Range Contributions to Neutrinoless Double-Beta Decay $I ¨ ^{-} \to I ¨ ^{+} ee$ at Physical Pion Mass

Peter Boyle, Felix Erben, Xu Feng +7

Neutrinoless double-beta ( $0 I^½ I^^{2} I^^{2}$ ) decays provide an excellent probe for determining whether neutrinos are Dirac or Majorana fermions. The short-range matrix elements associated…

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…

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…

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…
