Light and strange vector resonances from lattice QCD at physical quark masses / Boyle, Peter (Brookhaven ; Edinburgh U.) ; Erben, Felix (Edinburgh U. ; CERN) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Joswig, Fabian (Edinburgh U.) ; Lachini, Nelson Pitanga (Edinburgh U. ; Cambridge U., DAMTP) ; Marshall, Michael (Edinburgh U.) ; Portelli, Antonin (Edinburgh U. ; CERN ; RIKEN AICS, Kobe)
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 vector channel. [...]

Physical-mass calculation of $\rho(770)$ and $K^*(892)$ resonance parameters via $\pi \pi$ and $K \pi$ scattering amplitudes from lattice QCD / Boyle, Peter (Brookhaven ; Edinburgh U.) ; Erben, Felix (Edinburgh U. ; CERN) ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. (Edinburgh U.) ; Joswig, Fabian (Edinburgh U.) ; Lachini, Nelson Pitanga (Edinburgh U. ; Cambridge U., DAMTP) ; Marshall, Michael (Edinburgh U.) ; Portelli, Antonin (Edinburgh U. ; CERN ; RIKEN AICS, Kobe)
We present our study of the $\rho(770)$ and $K^*(892)$ resonances from lattice quantum chromodynamics (QCD) employing domain-wall fermions at physical quark masses. [...]

Semileptonic $D \rightarrow \pi \ell \nu$, $D \rightarrow K \ell \nu$ and $D_s \rightarrow K \ell \nu$ decays with 2+1f domain wall fermions / Marshall, Michael (Edinburgh U.) ; Boyle, Peter (Brookhaven ; Edinburgh U.) ; Del Debbio, Luigi (Edinburgh U.) ; Erben, Felix (Edinburgh U.) ; Flynn, Jonathan (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN) ; Portelli, Antonin (Edinburgh U.) ; Tsang, Justus Tobias (Southern Denmark U., CP3-Origins) ; Witzel, Oliver (Siegen U.)
We present the status of our project to calculate $D \to \pi \ell \nu$, $D \to K \ell \nu$ and $D_s \to K \ell \nu$ semileptonic form factors using domain wall fermions for both heavy and light quarks. Our computations are performed using RBC/UKQCD's set of 2+1 flavour domain wall fermion and Iwasaki gauge field ensembles. [...]

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.
