$K\pi$ scattering as a step towards $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ from Lattice QCD

Felix Erben, Matthew Black, Peter Boyle +7

Rare $b\to s{\ell }^{+}{\ell }^{-}$ decays provide some of the most sensitive tests of the Standard Model and require precise and systematically improvable hadronic input from lattice QCD. F…
