Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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].

Book excerpt: We report a search for B decays to selected final states with the [eta]c meson: B" 2!K"[eta]c[pi]+[pi]-, B" 2!K"[eta]c[omega], B" 2!K"[eta]c[eta] and B" 2!K"[eta]c[pi]0. The analysis is based on 772 × 106 BB-bar pairs collected at the [Upsilon](4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We set 90% confidence level upper limits on the branching fractions of the studied B decay modes, independent of intermediate resonances, in the range (0.6-5.3) × 10-4. We also search for molecular-state candidates in the D0D*-bar0 - D-bar0D*0, D0D-bar0 + D-bar0D0 and D*0D*-bar0 + D*-bar0D*0 combinations, neutral partners of the Z(3900)" and Z(4020)", and a poorly understood state X(3915) as possible intermediate states in the decay chain, and set 90% confidence level upper limits on the product of branching fractions to the mentioned intermediate states and decay branching fractions of these states in the range (0.6-6.9) × 10-5.

Book excerpt: 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.
