The next leading order corrections introduce substantial modifications to the naive factorization results (more than 50%). The branching ratio $Br(B\\to \\phi K)$ is predicted to be in the range $(F^{B\\to K}_1(m^2_\\phi)/0.33)^2(3.5\\sim 4.2) \\times 10^{-6}$ which is within the one $\\sigma$ allowed region from the central value of $6.2\\times 10^{-6}$ measured by CLEO, but outside the one $\\sigma$ allowed region from the central value of $17.2\\times 10^{-6}$ measured by BELLE for reasonable $F_1^{B\\to K}$. For the semi-inclusive decay $B\\to \\phi X_s$ we also include initial bound state effect in the heavy quark limit which decreases the branching ratio by about 10%. $Br(B\\to \\phi X_s)$ is predicted to be in the range $(5.1\\sim 6.3)\\times 10^{-5}$.", "revisions": [ { "version": "v2", "updated": "2000-08-20T06:09:27.000Z" } ], "analyses": { "keywords": [ "heavy quark limit", "initial bound state effect", "central value", "branching ratio", "naive factorization results" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
