Download Measurement of Branching Fractions and Charge Asymmetries in B Meson Decays to [eta]'K*, [eta]'[rho], and [eta][pi]. Book in PDF, ePub and Kindle
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 (

Download Measurement of Branching Fractions and Charge Asymmetries in B Decays to an Eta Meson and a K* Meson Book in PDF, ePub and Kindle
The authors present measurements of branching fractions and charge asymmetries for the decays B 2![eta]K*, where K8 indicates a spin 0, 1, or 2 K [pi] system. The data sample corresponds to 344 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider at SLAC. They measure the branching fractions (in units of 10−6): [Beta](B° 2![eta]K*°(892)) = 16.5 ± 1.1 ± 0.8, [Beta](B 2![eta]K*+(892)) = 18.9 ± 1.8 ± 1.3, [Beta](B° 2*0°) = 11.0 ± 1.6 ± 1.5, [Beta](B+ 20*+) = 18.2 ± 2.6 ± 2.6, [Beta](B° 2![eta]K*2°(1430)) = 9.6 ± 1.8 ± 1.1, and [Beta](B+ 2![eta]K*2+(1430)) = 9.1 ± 2.7 ± 1.4. They also determine the charge asymmetries for all decay modes.

Download Measurements of Branching Fractions and CP-Violating Asymmetries in B-Meson Decays to the Charmless Two-Body States K[sup 0]pi+, K-bar[sup 0]K[sup +], and K[sup 0]K-bar[sup 0]. Book in PDF, ePub and Kindle
The authors present preliminary measurements of the branching fraction and the CP-violating charge asymmetry in the B[sup +] --> K[sup 0][pi][sup +] decay, and a preliminary measurement of the branching fraction of the B[sup 0] --> K[sup 0][bar K][sup 0] decay. No evidence of direct CP violation in the B[sup +] --> K[sup 0][pi][sup +] mode is observed. The B[sup 0] --> K[sup 0][bar K][sup 0] measurement constitutes the first observation of this decay channel: the probability of obtaining the result assuming the null-signal hypothesis is 3.4 x 10[sup -6]. The authors have also searched for the B[sup +] --> [bar K][sup 0]K[sup +] decay and set an upper limit on its branching fraction at 2.35 x 10[sup -6] at the 90% C.L. The branching-fraction measurements reported here are consistent with previous measurements of the same quantities, but are extracted from a data sample larger by a factor of 2.6.

Download Measurements of the Branching Fractions and Charge Asymmetries of Charmless Three-Body Charged B Decays Book in PDF, ePub and Kindle
We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb[sup -1] of data collected at the[Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions[Beta](B[sup+][yields][pi][sup+][pi][sup -][pi][sup+])= (10.9[+-] 3.3[+-] 1.6) x 10[sup -6], [Beta](B[sup+][yields] K[sup+][pi][sup -][pi][sup+])= (59.1[+-] 3.8[+-] 3.2) x 10[sup -6], and[Beta](B[sup+][yields] K[sup+]K[sup -]K[sup+])= (29.6[+-] 2.1[+-] 1.6) x 10[sup -6], and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.

Download Measurement of Branching Fractions and Charge Asymmetries for Exclusive B Decays to Charmonium Book in PDF, ePub and Kindle
We report measurements of branching fractions and charge asymmetries 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 meson is either K or K*. We use a sample of about 124 million B{bar B} pairs collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.
