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.
