This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D*[sup[+-]] D[sup[-+]]. The measurement uses a data sample for approximately 88 million[Upsilon](4S)[yields] B[bar B] decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. They measure the branching fraction to be (8.8[+-] 1.0[+-] 1.3) x 10[sup -4] and the time-integrated CP-violating asymmetry between the rates to D*[sup -] D[sup+] and D*[sup+] D[sup -] to be[Alpha]= -0.03[+-] 0.11[+-] 0.05. They also measure the time-dependent CP-violating asymmetry parameters to be S[sub -+]= -0.24[+-] 0.69[+-] 0.12, C[sub -+]= -0.22[+-] 0.37[+-] 0.10 for B[yields] D*[sup -] D[sup+] and S[sub+-]= -0.82[+-] 0.75[+-] 0.14, C[sub+-]= -0.47[+-] 0.40[+-] 0.12 for B[yields] D*[sup+] D[sup -]. In each case the first error is statistical and the second error is systematic.
