Book Description
The 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})

Book Description
Using 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+.

Book Description
The authors present preliminary measurements of the B meson decays B[sup+][yields][eta][pi][sup+], B[sup+][yields][eta]K[sup+], and B[sup 0][yields][eta]K[sup 0]. The data were recorded with the BABAR detector at PEP II and correspond to 88.9 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+][yields][eta][pi][sup+])= (4.2[sub -0.9][sup+1.0][+-] 0.3) x 10[sup -6] and[Beta](B[sup+][yields][eta]K[sup+])= (2.8[sub -0.7][sup+0.8][+-] 0.2) x 10[sup -6]. They set a 90% CL upper limit of[Beta](B[sup 0][yields][eta]K[sup 0])

Book Description
The authors search for B° meson decays into two-body combinations of K°, [eta], [eta]', and [phi] mesons in 324 million B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider at SLAC. They measure the following branching fractions (upper limits at 90% confidence level) in units of 10−6: [Beta](B° 2![eta]K°) = 1.8{sub -0.6}{sup +0.7} ± 0.1 (
