英文摘要 | We present measurements of the branching fractions of the decays b+-->eta(')k(+) and b-0-->eta(')k(0). for b-0-->eta(')k(s)(0) we also measure the time-dependent cp-violation parameters (setaks0)-k-' and (cetaks0)-k-', and for b+-->eta(')k(+) the time-integrated charge asymmetry a(ch). the data sample corresponds to 88.9x10(6) b (b) over bar pairs produced by e(+)e(-) annihilation at the y(4s). the results are b(b+-->eta(')k(+))=(76.9+/-3.5+/-4.4)x10(-6), |
