| 英文摘要 | We report a search for b decays to selected final states with the eta (c) meson: b (+/-) -> k (+/-) eta (c) pi (+) pi (-), b-+/- -> k-+/-eta(c)pi(+)pi(-), b-+/- -> k-+/-eta(c)eta and b-+/- -> k-+/-eta(c)pi(0). the analysis is based on 772 x 10(6) b (b) over bar pairs collected at the gamma(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) x 10(-4). we also search for molecular-state candidates in the d-0 (d) over bar*(0) - (d) over bar (0) d*(0), d-0 (d) over bar (0) + (d) over bar (0) d-0 and d*(0) (d) over bar*(0) + d*(0) (d) over bar*(0) d*(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) x 10(-5). |
