摘要：
We consider effective Lagrangian models of CP-violating vertex structure in which a b -> uW vertex, proportional to s(13)e(-i delta 13) with s(13) very small (milliweak interaction) and 613 large, is dynamically generated. A consequent, enhanced CP-violating vertex for b -> sg results in an enhanced CP-violating phase in the ratio of amplitudes for (B) over bar (0)(B-0) -> phi K-S. We estimate that this can significantly change the S-parameter from the value expected in the standard model.
