Abstract
I discuss recent
progress in lattice calculations of $B \to D^{(*)} \ell \nu$
form factors, important for the precision
determination of $|V_{cb}|$ in the Standard Model (SM),
and for testing SM expectations of lepton flavor universality
in observables $R(D^{(*)})$.
I also discuss progress in calculations of the related
$b \to c$ semileptonic decays
$B_s \to D_s^{(*)} \ell \nu$ and $B_c \to J/\psi \, \ell \nu$
now experimentally accessible at the LHC.
