$B_s\to D_s^{(\ast )}$ form factors from lattice QCD with $N_f=2$ Wilson-clover quarks

Benoît Blossier, Pierre Henri Cahue, Jochen Heitger +3

We report on a two-flavour lattice QCD determination of the $B_s\to D_s$ and $B_s\to D_s^{\ast }$ transitions, which in the heavy quark limit can be parameterised by the form factors $\m…
