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+.

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] (

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})

We present preliminary results of a search for the decay B[sup 0] [yields] [eta][prime][phi]. The data were recorded with the BABAR detector at the PEP-II asymmetric-energy B-meson Factory at SLAC and correspond to 89 million B[bar B] pairs produced in e[sup +]e[sup -] annihilation at the [Upsilon](4S) resonance. We find no evidence for a signal and set a 90% CL upper limit of [Beta](B[sup 0] [yields] [eta][prime][psi])

The authors report a study of the B meson decays, B[sup+][yields] J/[psi][phi]K[sup+], B[sup 0][yields] J/[psi][phi]K[sub S][sup 0], B[sup 0][yields] J/[psi][phi], B[sup 0][yields] J/[psi][eta] and B[sup 0][yields] J/[psi][eta][prime] using 56 million B[bar B] events collected at the[Upsilon](4S) resonance with the BABAR detector at the PEP-II e[sup+]e[sup -] asymmetric-energy storage ring. They measure the branching fractions[Beta](B[sup+][yields] J/[psi][phi]K[sup+])= (4.4[+-] 1.4(stat)[+-] 0.5(syst)) x 10[sup -5] and[Beta](B[sup 0][yields] J/[psi][phi]K[sub S][sup 0])= (5.1[+-] 1.9(stat)[+-] 0.5(syst)) x 10[sup -5], and set upper limits at 90% confidence level for the branching fractions[Beta](B[sup 0][yields] J/[psi][phi])
