Abstract

We study BηXsB \to \eta' X_s within the framework of the Standard Model. Several mechanisms such as bηsgb \to \eta' s g from the QCD anomaly, and bηsb \to \eta's and BηsqˉB\to \eta' s \bar q from four-quark operators are treated simultaneously. We find that the first mechanism give a significant contribution to the branching ratio for BηXsB\to \eta' X_s, while the other two mechanisms account for about 15% of the experimental value. The Standard Model prediction for BηXsB\to \eta' X_s is consistent with the CLEO data.
