Enhanced $b\to sg$ Decay, Inclusive ${\eta }^{\prime }$ Production, and the Gluon Anomaly

Wei-Shu Hou, B. Tseng

The experimental hint of large $B\to {\eta }^{\prime }+X_s$ is linked to the $b\to s$ penguins via the gluon anomaly. Using running ${\alpha }_s$ in the ${\eta }^{\prime }$-$g$-$g$ coupling, the standard…
