Query: Finite mass corrections for B -> D(*), D** \ell \nu decays in the
  Bakamjian-Thomas relativistic quark model   The Bakamjian-Thomas relativistic quark model for hadron current matrix
elements, while non-covariant at finite mass, is successful in the heavy quark
limit : form factors are covariant and satisfy Isgur-Wise scaling and
Bjorken-Uraltsev sum rules. Motivated by the so-called "1/2 vs. 3/2 puzzle" in
B decays to positive parity D**, we examine the implications of the model at
finite mass. In the elastic case 1/2^- -> 1/2^-, the HQET constraints for the
O(1/m_Q) corrections are analytically fulfilled. A number of satisfying
regularities is also found for inelastic transitions. We compute the form
factors using the wave functions given by the Godfrey-Isgur potential. For
1/2^- \to 3/2^+ the departures from the heavy quark limit are small, but we
find a strong enhancement in 1/2^- -> 1/2^+ (for 0^- -> 0^+). This enhancement
is linked to a serious difficulty of the model at finite mass for the inelastic
transitions, namely a violation of the HQET constraints at zero recoil
formulated by Leibovich et al. These are nevertheless satisfied in the
non-relativistic limit for the light quark. We conclude that these HQET
rigorous constraints are crucial in the construction of a sensible relativistic
quark model of inelastic form factors.
