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. [...]

New strategies for probing $B\to D^\ast \ell\bar\nu_\ell$ lattice and experimental data / Bordone, Marzia (CERN) ; Juttner, Andreas (U. Southampton (main) ; CERN)
We present an analysis of the exclusive semileptonic decay $B\to D^\ast \ell\bar\nu_\ell$ based on the Belle and Belle II data made public in 2023, combined with recent lattice-QCD calculations of the hadronic transition form factors by FNAL/MILC, HPQCD and JLQCD. [...]

With the development of lattice QCD in recent years, a determination of decay rates for inclusive semileptonic decays from lattice correlators now seems viable. [...]

Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the opportunities these experiments and theoretical developments provide for particle physics in the coming decade and beyond.

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 $|V_{ub}|$.

Bayesian inference for form-factor fits regulated by unitarity and analyticity / Flynn, J.M. (Southampton U.) ; Jüttner, A. (Southampton U. ; CERN) ; Tsang, J.T. (CERN)
We propose a model-independent framework for fitting hadronic form-factor data, which is often only available at discrete kinematical points, using parameterisations based on to unitarity and analyticity. In this novel approach the latter two properties of quantum-field theory regulate the ill-posed fitting problem and allow model-independent predictions over the entire physical range. [...]

Exclusive semileptonic $B_s\to K \ell \nu$ decays on the lattice / Flynn, J.M. (Southampton U.) ; Hill, R.C. (Edinburgh U.) ; Jüttner, A. (Southampton U. ; CERN) ; Soni, A. (Brookhaven) ; Tsang, J.T. (CERN) ; Witzel, O. (U. Siegen (main)) /RBC/UKQCD Collaboration
Semileptonic $B_s \to K \ell \nu$ decays provide an alternative $b$-decay channel to determine the CKM matrix element $|V_{ub}|$, and to obtain a $R$-ratio to investigate lepton-flavor-universality violations. Results for the CKM matrix element may also shed light on the discrepancies seen between analyses of inclusive or exclusive decays. [...]

The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators / Asmussen, Nils (Southampton U.) ; Erben, Felix (Piemonte Orientale U., Alessandria ; INFN, Turin) ; Flynn, Jonathan (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN) ; Mukherjee, Rajnandini (Southampton U.) ; Sachrajda, Christopher T. (Southampton U.)
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. [...]

Update of Euclidean windows of the hadronic vacuum polarization / RBC Collaboration
We compute the standard Euclidean window of the hadronic vacuum polarization using multiple independent blinded analyses. We improve the continuum and infinite-volume extrapolations of the dominant quark-connected light-quark isospin-symmetric contribution and address additional sub-leading systematic effects from sea-charm quarks and residual chiral-symmetry breaking from first principles.
