We present results showing that Domain Wall fermions are a suitable discretisation for the simulation of heavy quarks. This is done by a continuum scaling study of charm quarks in a M\"obius Domain Wall formalism using a quenched set-up. [...]

We present scaling studies for heavy-quark observables calculated with an $O(a^2)$-improved fermion action on tree-level Symanzik improved gauge configurations. Lattices of $1/a = $ 2.0-3.8 GeV with an equal physical volume 1.6 fm are used. [...]

Improved lattice fermion action for heavy quarks

Adv. Studies) ; Marinkovic, Marina (CERN ; Southampton U.) ; Noaki, Jun-Ichi (KEK, Tsukuba) ; Tsang, Justus Tobias (Southampton U.)
We develop an improved lattice action for heavy quarks based on Brillouin-type fermions, that have excellent energy-momentum dispersion relation. The leading discretization errors of $O(a)$ and $O(a^2)$ are eliminated at tree-level. [...]

Charm physics with physical light and strange quarks using domain wall fermions
/ Jüttner, Andreas (Southampton U.) ; Del Debbio, Luigi (Edinburgh U.) ; Garron, Nicolas (Cambridge U., DAMTP) ; Khamseh, Ava (Edinburgh U.) ; Marinkovic, Marina (Southampton U. ; CERN) ; Sanfilippo, Francesco (Southampton U.) ; Tsang, Justus Tobias (Southampton U.) ; Boyle, Peter A. (Edinburgh U.)
We present a study of charm physics using RBC/UKQCD 2+1 flavour physical point domain wall fermion ensembles for the light quarks as well as for the valence charm quark. After a brief motivation of domain wall fermions as a suitable heavy quark discretisation we will show first results for masses and matrix elements..

BSM $B - \bar{B}$ mixing on JLQCD and RBC/UKQCD $N_f=2+1$ DWF ensembles
/ Boyle, Peter (U. Edinburgh, Higgs Ctr. Theor. Phys. ; Brookhaven) ; Erben, Felix (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Jüttner, Andreas (Southampton U. ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba) ; Marshall, Michael (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Portelli, Antonin (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Witzel, Oliver (U. Siegen (main)) ; Del Debbio, Luigi (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Tsang, Justus Tobias (Southern Denmark U., CP3-Origins)
We are presenting our ongoing Lattice QCD study on $B - \bar{B}$ mixing on several RBC/UKQCD and JLQCD ensembles with 2+1 dynamical-flavour domain-wall fermions, including physical-pion-mass ensembles. We are extracting bag parameters $B_{B_d}$ and $B_{B_s}$ using the full 5-mixing-operator basis to study both Standard-Model mixing as well as Beyond the Standard Model mixing, using a fully correlated combined fit to two-point functions and ratios of three-point and two-point functions.

Studies on finite-volume effects in the inclusive semileptonic decays of charmed mesons
/ Kellermann, Ryan (Sokendai, Tsukuba ; KEK, Tsukuba) ; Barone, Alessandro (U. Mainz, PRISMA ; U. Southampton (main)) ; Hashimoto, Shoji (Sokendai, Tsukuba ; KEK, Tsukuba) ; Jüttner𝑐, Andreas (U. Southampton (main) ; CERN) ; Kaneko𝑎, Takashi (CERN ; KMI, Nagoya ; Sokendai, Tsukuba ; KEK, Tsukuba)
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 were approximately tuned to the physical values. [...]

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 strange contribution to $a_{\mu}$ with physical quark masses using Möbius domain wall fermions
/ Spraggs, Matt (Southampton U.) ; Boyle, Peter (Edinburgh U.) ; Del Debbio, Luigi (Edinburgh U.) ; Jüttner, Andreas (Southampton U.) ; Lehner, Christoph (Brookhaven) ; Maltman, Kim (Adelaide U. ; York U., Canada) ; Marinkovic, Marina (CERN) ; Portelli, Antonin (Southampton U. ; Brookhaven)
We present preliminary results for the strange leading-order hadronic contribution to the anomalous magnetic moment of the muon using RBC/UKQCD physical point domain wall fermions ensembles. We discuss various analysis strategies in order to constrain the systematic uncertainty in the final result..
