Book Description
Recent measurements in exclusive hadronic B decays to states with charm are presented, including a review of the B {yields} D{sub sJ}D{sup (*)} decays, and a study of the B{sup -} {yields} J/{psi} K{sup -} {pi}{sup +}{pi}{sup -} decay looking for charmonium resonances. New results are shown on the search of the B{sup 0} {yields} D{sub s}{sup +} {rho}{sup -} and B{sup 0} {yields} J/{psi}{gamma} decays. These analysis are based on the 1999-2003 dataset collected by the BABAR experiment at the PEP-II e{sup +}e{sup -} storage ring at the Stanford Linear Accelerator Center.

Book Description
In this paper recent results in the field of B meson decays to states containing charm are presented. These analyses are based on the 1999-2003 dataset collected by the BABAR experiment at the PEP-II ee− storage ring at the Stanford Linear Accelerator Center. Special attention is devoted to B decays to final states containing D mesons. In addition a few new results from B decays to charmonium states are reported.

Book Description
In this paper the studies of three different B decays to hadronic states are presented. These results are based on 1999-2003 dataset collected by the BABAR experiment at the PEP-II ee− storage ring at the Stanford Linear Accelerator Center. The measurements are the hadronic branching fraction of B 2!J/[Psi]p{bar {Lambda}}, B° 2!J/[Psi]p{bar p}, B° 2!D*{sup {+-}} D{sup {-+}}, and the direct CP-asymmetry in B° 2!D°(CP)K− channels.

Book Description
A wealth of new measurements of hadronic B decays to open charm and charmonium have been performed on the data sample collected by the BaBar experiment at the PEP-II e{sup +}e{sup -} B-factory. We report the first measurement of the rates for inclusive charm production separately for charged and neutral B mesons. Combining measurements of the decay rate of B{sup 0} {yields} D*{sub s}{sup +}D*{sup -} obtained with a partial reconstruction technique and the complete reconstruction of B{sup 0} {yields} D*{sub s}{sup +}D*{sup -} with D{sub s}{sup +} {yields} {phi}{pi}{sup +}, we obtain the most precise measurement of {Beta}(D{sub s}{sup +} {yields} {phi}{pi}{sup +}). We present an update of the measurements of the branching fractions of exclusive B decays to J/{psi}, {psi}(2S), {chi}{sub c1}, {chi}{sub c2} and a kaon or a K*. In addition, we show preliminary results on exclusive decay rates to final states with baryons, or newly-discovered particles, such as D*{sub sJ}(2317), D{sub sJ}(2460){sup +}, and the X(3872).

Book Description
Since it began recording data in 1999, the BaBar detector at the SLAC B Factory has collected nearly 90 million B meson pairs. Using this sample, they are able to make precise measurements of B decays to open charm and charmonium. In particular, they have measured the rates for B [yields] D[bar D]K, for the color-suppressed modes B[sup 0] [yields] D[sup 0][pi][sup 0], B[sup 0] [yields] D[sup 0][eta], and B[sup 0] [yields] D[sup 0][omega], for B[sup +] [yields] [chi][sub c][sup 0]K[sup +], and for B[sup 0] [yields] D(*)[sub s][sup +] D*[sup -]. They have also begun preparations for a measurement of the CKM angle [gamma] by studying the modes B[sup +] [yields] D[sup 0]K[sup +], B[sup 0] [yields] D(*)[sub s][sup +] [pi][sup -], and B[sup 0] [yields] D(*)[sub s][sup +] K[sup -].

Book Description
The authors report preliminary results on the measurement of branching fractions of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/[psi], [psi](2S) and [chi][sub c1], and the light mesons are either K or K*. They use a sample of about 124 million B[bar B] events collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.
