$B\to D^{\ast }$ vector, axial-vector and tensor form factors for the full $q^2$ range from lattice QCD

Judd Harrison, Christine T. H. Davies

We compute the complete set of SM and tensor $B_{(s)}\to D_{(s)}^{\ast }\ell \bar{\nu }$ semileptonic form factors across the full kinematic range of the decay using second generation MILC $n_…
