Query: Lattice computation of $B \to D^*,\;D^{**}\ell \nu$ form factors at
  finite heavy masses   We propose a strategy to compute form factors entering the semileptonic decay
channel of $B$ mesons into orbitally excited (P wave) $D^{**}$ charmed mesons
on the lattice using, for the first time, realistic charm quarks having a
finite mass. We present preliminary results about the extracted transition
amplitudes and form factors at different recoils and at three different $b$
quark masses.
