Available in PDF, EPUB and Kindle. Book excerpt: 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.).
