    “…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. …”

    “…Our results, which cover the typical gauge coupling range of large-volume $N_\mathrm{f}=2+1$ QCD simulations with Wilson fermions at lattice spacings below $0.1\,\mathrm{fm}$ , are of particular use for the non-perturbative calculation of $\mathrm{O}(a)$ improved renormalised quark masses.…”
