Measurement of CP-Violating Asymmetries in B0->D(*)+D-

We present updated measurements of \CP-violating asymmetries in the decays $\text{Bz}\to \text{Dstarpm}\text{Dmp}$ and $\text{Bz}\to \text{Dp}\text{Dm}$ using $(383\pm 4)\times {10}^6\text{BB}$ pairs collected by the \babar detector at the PEP-II $B$ factory. We determine the time-integrated \CP asymmetry ${$\mathcal{A}$}{\Dstarpm\Dmp}=0.12\pm 0.06\pm 0.02$,andthetime-dependentasymmetryparameterstobe$C{\Dstarp\Dm} =0.18\pm 0.15\pm 0.04$,$S_{\Dstarp\Dm}=-0.79\pm 0.21\pm 0.06$,$C_{\Dstarm\Dp} =0.23\pm 0.15\pm 0.04$,$S_{\Dstarm\Dp} =-0.44\pm 0.22\pm 0.06$,$C_{\Dp\Dm} =0.11\pm 0.22\pm 0.07$,and$S_{\Dp\Dm} =-0.54\pm 0.34\pm 0.06$, where the first uncertainty is statistical and the second is systematic.
