Continuum limit of the leading order HQET form factor in $B_s\to K\ell \nu$ decays

Felix Bahr, Debasish Banerjee, Fabio Bernardoni +4

We discuss the computation of form factors for semi-leptonic decays of $\mathrm{B}$-, ${\mathrm{B}}_{\mathrm{s}}$- mesons in lattice QCD. Considering in particular the example of the static ${\mathrm{B}}_{\mathrm{s}}$ for…
