| 英文摘要 | We study B-->phiK and B-->phiX(s) decays in the heavy quark limit using perturbative QCD. The next leading order corrections introduce substantial modifications to the naive factorization results (more than 50%). The branching ratio Br(B-->phiK) is predicted to be in the range [F-1(B-->K)(m(phi)(2))/0.33](2)(3.2-4.5)x10(-6) that is within the one sigma allowed region from the central value of 6.2x10(-6) measured by CLEO Collaboration, but outside the one sigma allowed region from the central value of 17.2x10(-6) measured by BELLE Collaboration for reasonable F-1(B-->K). For the semi-inclusive decay B-->phiX(s) we also include initial bound state effects in the heavy quark limit that decreases the branching ratio by about 10%. Br(B-->phiX(s)) is predicted to be in the range (4.8-6.6)x10(-5). |
