$B\to \ddot{I}€$, $B_{(s)}\to D_{(s)}$ from 2+1+1 Flavor Lattice QCD

Nicholas Cassar, Akhil Chauhan, Carleton DeTar +8

We present a lattice-QCD calculation of the hadronic form factors for $B$-meson semileptonic decays computed using the highly improved staggered quark action for both valence and s…
