| dc.description | The charm content in $η'$ is estimated using the QCD U(1) axial anomaly applied to $b\to s g g \to η' s$. We find $f_{η'}^{(c)} \approx - 3.1$ MeV for $m_c = 1.3$ GeV. Our estimate agrees with other independent methods by Feldmann and Kroll, and Araki, Musakhanov and Toki. The resulting branching ratios for $B \to η' K$ in the generalized factorization model are marginally consistent with the CLEO data, although they are lower than the data by $\sim 2$. | |
