| 英文摘要 | We report measurements for two-body charmless hadronic b decays with an eta ' meson in the final state. using 11.1 x 10(6) b (b) over bar pairs collected with the belle detector, we find bf(b(+) --> eta 'k(+)) = (79(-11)(+12) +/- 9) x 10(-6) and bf(b(0) --> eta 'k(0)) = (55(-16)(+19) +/- 8) x 10(-6), where the first and second errors are statistical and systematic, respectively. no signal is observed in the mode b+ q'7r+, and we set a90% confidence level upper limit of bf(b+ - q'7r+) < 7 x 10-6. the cp asymmetry in b( |
