Description
We report on a two-flavor lattice QCD determination of the $B_s \to D_s$
and $B_s \to D^*_s$ transitions, which in the heavy quark limit can be
parameterized by the form factors ${\cal G}$, and $h_{A_1}$, $h_{A_2}$ and
$h_{A_3}$. In the search of New Physics through tests of lepton-flavour
universality, $B_s$ decay channels are complementary to $B$ decays and
widely studied at $B$ factories and LHCb. The purpose of our study is to
explore a suitable method to extract form factors associated with $b \to c$
currents from lattice QCD. In particular, we present numerical results for
${\cal G}$ and $h_{A_1}$.
