Book Description
The authors present measurements of branching fractions and charge asymmetries in B-meson decays to [rho][sup +][pi][sup 0], [rho][sup 0][pi][sup +] and [rho][sup 0][pi][sup 0]. The data sample comprises 89 x 10[sup 6] [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetries-energy B Factory at SLAC. They find the charge-averaged branching fractions [Beta](B[sup +] [yields] [rho][sup +][pi][sup 0]) = (10.9 [+-] 1.9(stat) [+-] 1.9(syst)) x 10[sup -6] and [Beta](B[sup +] [yields] [rho][sup 0][pi][sup +]) = (9.5 [+-] 1.1 [+-] 0.8) x 10[sup -6], and they set a 90% confidence-level upper limit [Beta](B[sup 0] [yields] [rho][sup 0][pi][sup 0])

Book Description
The authors present preliminary measurements of branching fractions and charge asymmetries for the B meson decays B[yields][eta][prime] K*, B[yields][eta][prime][rho], and B[sup+][yields][eta][prime][pi][sup+]. The data were recorded with the BABAR detector at PEP-II and correspond to 89 x 10[sup 6] B[bar B] pairs produced in e[sup+]e[sup -] annihilation through the[Upsilon](4S) resonance. They find the branching fractions[Beta](B[sup 0][yields][eta]K*[sup 0])= (19.0[sub -2.1][sup+2.2][+-] 1.3) x 10[sup -6], [Beta](B[sup+][yields][eta]K*[sup+])= (25.7[sub -3.6][sup+3.8][+-] 1.8) x 10[sup -6] with 90% confidence, and[Beta](B[sup+][yields][eta][prime][pi][sup+])= (2.8[sub -1.0][sup+1.3][+-] 0.3) x 10[sup -6] (

Book Description
The authors present preliminary measurements of branching fractions and charge asymmetries for the B meson decays B 2![eta]' K*, B 2![eta]'[rho], and B 2![eta]'[pi]. The data were recorded with the BABAR detector at PEP-II and correspond to 89 x 106 B{bar B} pairs produced in e+e− annihilation through the [Upsilon](4S) resonance. They find the branching fractions [Beta](B° 2![eta]K*°) = (19.0{sub -2.1}{sup +2.2} ± 1.3) x 10−6, [Beta](B+ 2![eta]K*+) = (25.7{sub -3.6}{sup +3.8} ± 1.8) x 10−6 with 90% confidence, and [Beta](B+ 2![eta]'[pi]+) = (2.8{sub -1.0}{sup +1.3} ± 0.3) x 10−6 (

Book Description
Based on a sample of 227 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the branching fraction?(B° →?°?°) = (1.17 ± 0.32 ± 0.10) x 10−6, and the asymmetry C{sub?°?°} = -0.12 ± 0.56 ± 0.06. The B° →?°?° signal has a significance of 5.0?. We also measure?(B →?+?°) = (5.8 ± 0.6 ± 0.4) x 10−6,?(B+ → K+?°) = (12.0 ± 0.7 ± 0.6) x 10−6, and the charge asymmetries?{sub?+{pi}°} = -0.01 ± 0.10 ± 0.02 and?{sub K{sup +}{pi}°} = 0.06 ± 0.06 ± 0.01. Using isospin relations we find an upper bound on the angle difference.

Book Description
The authors study the decays B° → J/???− and B+ → J/??+?°, including intermediate resonances, using a sample of 382 million B{bar B} pairs recorded by the BABAR detector at the PEP-II e+e− B factory. They measure the branching fractions?(B° → J/??°) = (2.7 ± 0.3 ± 0.17) x 10−5 and?(B+ → J/??+) = (5.0 ± 0.7 ± 0.31) x 10−5. The authors also set the following upper limits at the 90% confidence level:?(B° → J/??+?− non-resonant)
