Aubert, B. et al. (2006) Measurement of time-dependent CP asymmetries in B0→D(*)±π∓ and B0→D±ρ∓ decays. Physical Review D, 73 (11). p. 111101. ISSN 1550-7998

We present updated results on time-dependent CP asymmetries in fully reconstructed B0→D(*)±π∓ and B0→D±ρ∓ decays in approximately 232×106 Υ(4S)→BB̅ 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 2β+γ: aDπ=-0.010±0.023±0.007, clepDπ=-0.033±0.042±0.012, aD*π=-0.040±0.023±0.010, clepD*π=0.049± 0.042±0.015,aDρ=-0.024±0.031±0.009, clepDρ=-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⁡(2β+γ)|>0.64  (0.40) at 68% (90%) confidence level.
