英文摘要 | We report the results of searches for b+ -> j/psi eta'k+ and b-0 -> j/psi eta'k-s(0) decays, using a sample of 388 x 10(6) b (b) over bar b pairs collected with the belle detector at the y(4s) resonance. no statistically significant signal is found for either of the two decay modes and upper limits for the branching fractions are determined to be b(b+ -> j/psi eta k-'(+)) < 8: 8 x 10(-5) and b(b-0 -> j/psi eta'k-s(0)) < 2.5 x 10(-5) at 90% confidence level. |
