Measurement of Time-dependent CP Asymmetries inB0->D(*)pi and B0->Drho Decays

We present updated results on time-dependent CP asymmetries in fully reconstructed B{sup 0} {yields} D{sup (*){+-}}{pi}{sup {-+}} and B{sup 0} {yields} D{sup {+-}}{rho}{sup {-+}} decays in approximately 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. From a time-dependent maximum likelihood fit we obtain for the parameters related to the CP violation angle 2{beta} + {gamma}: a{sup D{pi}} = -0.010 {+-} 0.023 {+-} 0.007, c{sub lep}{sup D{pi}} = -0.033 {+-} 0.042 {+-} 0.012, a{sup D*{pi}} = -0.040 {+-} 0.023 {+-} 0.010, C{sub lep}{sup D*{pi}} = 0.049 {+-} 0.042 {+-} 0.015, a{sup D{rho}} = -0.024 {+-} 0.031 {+-} 0.009, c{sub lep}{sup D{rho}} = -0.098 {+-} 0.055 {+-} 0.018, where the first error is statistical and the second is systematic. Using other measurements and theoretical assumptions, we interpret the results in terms of the angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle and find |sin(2{beta}+{gamma})| > 0.64 (0.40) at 68% (90%) confidence level
