DOWNLOAD EBOOKUsing 383 million B{bar B} pairs from the BABAR data sample, they report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K{bar K}* or [eta][pi][pi] final states with mass in the range (1.2-1.8) GeV/c2. They observe a significant enhancement at the low K{bar K}* invariant mass which is interpreted as B 2K, find evidence for the decay B+ 2K+, and place upper limits on the decays B+ 2K+, B+ 2!f1(1285)K+, B+ 2!f1(1420)K+, and B+ 2K+.

DOWNLOAD EBOOKWe present the results of searches for B decays to charmless two-body final states containing [eta] or [omega] mesons, based on 20.7 fb−1 of data collected with the BABAR detector. We find the branching fractions [Beta](B 2![eta] K) = (70 ± 8 ± 5) x 10−6, [Beta](B° 2![eta] K°) = (42−11{sup +13} ± 4) x 10−6, and [Beta](B+ 2![omega][pi]+) = (6.6{sub -1.8}{sup +2.1} ± 0.7) x 10−6 where the first error quoted is statistical and the second systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are [Beta](B° 2![omega] K°)

DOWNLOAD EBOOKThe authors describe searches for decays of B mesons to the charmless final states {eta}'{eta}'K. The data consist of 228 million B{bar B} pairs produced in e{sup +}e{sup -} annihilation, collected with the BABAR detector at the Stanford Linear Accelerator Center. The 90% confidence level upper limits for the branching fractions are {Beta}(B{sup 0} {yields} {eta}'{eta}'K{sup 0})

DOWNLOAD EBOOKWe describe studies of the decays of B mesons to final states [eta]K{sup *}(892), [eta]K{sup *}0(S-wave), [eta]K{sup *}2(1430), and [eta]'K based on data collected with the BABAR detector at the PEP-II asymmetric-energy ee− collier at the Stanford Linear Accelerator Center. We measure branching fractions and charge asymmetries for the decays B 2![eta]K{sup *}, where K{sup *} indicates a spin 0, 1, or 2 K[pi] system, making first observations of decays to final states [eta]K{sup *0}0(S-wave), [eta]K{sup *+}0 (S-wave), and [eta]K{sup *0}2(1430). We measure the time-dependent CP-violation parameters S and C for the decays B° 2![eta]'K°, observing CP violation in a charmless B decay with 5[sigma] significance considering both statistical and systematic uncertainties.
