Inclusive semileptonic decays from lattice QCD: analysis of systematic effects
/ Kellermann, Ryan (KEK, Tsukuba) ; Hu, Zhi (KEK, Tsukuba) ; Barone, Alessandro (U. Mainz, PRISMA) ; Elgaziari, Ahmed (U. Southampton (main)) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba) ; Jüttner, Andreas (U. Southampton (main) ; CERN)
Lattice QCD calculations of inclusive semileptonic decay rates involve new types of systematic effects, such as truncation errors in the estimation of energy integrals, or finite-volume effects for multi-body final states. We investigate them for the lattice data of $D_s \to X_s \ell\nu$ decays, obtained using Möbius domain-wall fermions. [...]

Systematic effects in the lattice calculation of inclusive semileptonic decays
/ Kellermann, Ryan (KEK, Tsukuba) ; Barone, Alessandro (U. Mainz, PRISMA) ; Elgaziari, Ahmed (U. Southampton (main)) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Hu, Zhi (KEK, Tsukuba) ; Jüttner, Andreas (U. Southampton (main) ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; KMI, Nagoya)
We report on the calculation of the inclusive semileptonic decay of the $D_s$ meson on the lattice. We simulate the $D_s \rightarrow X_s\ell\nu_\ell$ process with Möbius domain-wall charm and strange quarks, whose masses are approximately tuned to their physical values. [...]

Chebyshev and Backus-Gilbert reconstruction for inclusive semileptonic $B_{(s)}$-meson decays from Lattice QCD
/ Barone, Alessandro (U. Mainz, PRISMA ; Southampton U.) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Jüttner, Andreas (Southampton U. ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba ; KMI, Nagoya) ; Kellermann, Ryan (KEK, Tsukuba ; Sokendai, Tsukuba)
We present a study on the nonperturbative calculation of observables for inclusive semileptonic decays of $B_{(s)}$ mesons using lattice QCD. We focus on the comparison of two different methods to analyse the lattice data of Euclidean correlation functions, specifically Chebyshev and Backus-Gilbert approaches. [...]

Approaches to inclusive semileptonic B$_{(s)}$-meson decays from Lattice QCD
/ Barone, Alessandro (Southampton U. ; KEK, Tsukuba) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Jüttner, Andreas (Southampton U. ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba ; KMI, Nagoya) ; Kellermann, Ryan (KEK, Tsukuba ; Sokendai, Tsukuba)
We address the nonperturbative calculation of the inclusive decay rate of semileptonic $B_{(s)}$-meson decays from lattice QCD. Precise Standard-Model predictions are key ingredients in searches for new physics, and this type of computation may eventually provide new insight into the long-standing tension between the inclusive and exclusive determinations of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements $|V_{cb}|$ and $|V_{ub}|$.

The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators

We present our calculations for the $I$ = 1/2 and 3/2 $K-\pi$ s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functions. We use the domain wall fermion action with physical quark masses at a single lattice spacing. [...]

Isospin-breaking corrections to light leptonic decays in lattice QCD+QED at the physical point
/ Hermansson-Truedsson, Nils (U. Bern, AEC ; Lund U., Dept. Theor. Phys.) ; Boyle, Peter (Edinburgh U. ; Brookhaven) ; Di Carlo, Matteo (Edinburgh U.) ; Erben, Felix (Edinburgh U.) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Harris, Tim (Edinburgh U.) ; Hodgson, Raoul (Edinburgh U.) ; Jüttner, Andreas (CERN ; Southampton U.) ; hÓgáin, Fionn Ó. (Edinburgh U.) et al.
We report on the physical-point RBC/UKQCD calculation of the leading isospin-breaking corrections to light-meson leptonic decays. This is highly relevant for future precision tests in the flavour physics sector, in particular the first-row unitarity of the Cabibbo-Kobayashi-Maskawa matrix containing the elements $V_{us}$ and $V_{ud}$.
