$B_s\to D_s^{\ast }$ Form Factors for the full $q^2$ range from Lattice QCD

Judd Harrison, Christine T. H. Davies

We compute the Standard Model semileptonic vector and axial-vector form factors for $B_s\to D_s^{\ast }$ decay across the full $q^2$ range using lattice QCD. We use the Highly Improved S…
