Book Description
We present results of a search for the X(3872) in B° → X(3872)K{sub S}°, X(3872) → J/???−, improved measurements of B− → X(3872)K−, and a study of the J/??+?− mass region above the X(3872). We use 232 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II e+e− asymmetric-energy storage rings. The results include the 90% confidence interval 1.34 x 10−6

Book Description
We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/[psi][pi][sup+][pi][sup -]. The data set contains approximately 56 million B[bar B] pairs produced at the[Upsilon](4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e[sup+]e[sup -] storage ring. The result of this analysis is[Beta](B[sup 0][yields] J/[psi][pi][sup+][pi][sup -])= (4.6[+-] 0.7[+-] 0.6) x 10[sup -5], where the first error is statistical and the second is systematic. In addition we measure[Beta](B[sup 0][yields] J?[psi][rho][sup 0])= (1.6[+-] 0.6[+-] 0.4) x 10[sup -5].

Book Description
We have studied the B{sup ±} → J/[psi][pi]{sup ±} and B{sup ±} → J/[psi] K{sup ±} decays using a 20.7 fb−1 data set collected with the BABAR detector. We observe a signal of 51 ± 10 B{sup ±} → J/[psi][pi]{sup ±} events and determine the ratio [Beta](B{sup {+-}} → J/[psi][pi]{sup {+-}})/[Beta](B{sup {+-}} → J/[psi] K{sup {+-}}) to be [3.91 {+-} 0.78(stat.) {+-} 0.19(syst.)]%. The CP-violating charge asymmetries for the B{sup {+-}} → J/[psi] [pi]{sup {+-}} and B{sup {+-}} → J/[psi] K{sup {+-}} decays are determined to be [Alpha]{sub {pi}} = 0.01 {+-} 0.22(stat.) {+-} 0.01(syst.) and [Alpha]{sub K} = 0.003 {+-} 0.030(stat.) {+-} 0.004(syst.).
