Lattice computation of $B \to D^*,\;D^{**}\ell ν$ form factors at
finite heavy masses    [PDF]

Mariam Atoui

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.
