Extraction of $B_s\to D_s^{(\ast )}$ form factors from $N_f=2$ lattice QCD

Benoît Blossier, Pierre-Henri Cahue, Jochen Heitger +3

We report on a two-flavour lattice QCD study of the $B_s\to D_s$ and $B_s\to D_s^{\ast }$ transitions parameterized, in the heavy quark limit, by the form factors $\mathcal{G}$, and $h_{A…
