Query: Measurement of CP-violating parameters in fully reconstructed $B\to
  D^{(*)}\pi$ and $B\to D\rho$ decays   We present a preliminary measurement of CP-violating asymmetries in fully
reconstructed $B^0{\to}D^{(*)\pm}\pi^{\mp}$ and $\B^0{\to}D^{\pm}\rho^{\mp}$
decays in approximately 110 million $\Upsilon(\rm 4S) \to B\bar{B}$ decays
collected with the BaBar detector at the PEP-II asymmetric-energy $B$ factory
at SLAC. % From a maximum likelihood fit to the time-dependent decay
distributions we obtain for the CP-violating parameters: $a^{D\pi} =
-0.032\pm0.031 (\textrm{stat.})\pm 0.020 (\textrm{syst.}), c_{\rm lep}^{D\pi} =
-0.059\pm0.055 (\textrm{stat.})\pm 0.033 (\textrm{syst.})$ on the
$B^0{\to}D^{\pm}\pi^{\mp}$ sample, $a^{D^*\pi} = -0.049\pm0.031
(\textrm{stat.})\pm 0.020 (\textrm{syst.}), c_{\rm lep}^{D^*\pi} =
+0.044\pm0.054 (\textrm{stat.})\pm 0.033 (\textrm{syst.})$ on the
$B^0{\to}D^{*\pm}\pi^{\mp}$ sample, and $a^{D\rho} = -0.005\pm0.044
(\textrm{stat.})\pm 0.021 (\textrm{syst.}), c_{\rm lep}^{D\rho} =
-0.147\pm0.074 (\textrm{stat.})\pm 0.035 (\textrm{syst.})$ on the
$B^0{\to}D^{\pm}\rho^{\mp}$ sample.
