Abstract :
We propose that the dominant fraction of the B → η′ + Xs rate is due mainly to b → sg∗, where g∗ is an off-shell gluon, followed by g∗ → gη′ via the anomalous coupling of the η′ to two gluons. The calculated rate for B → η′ + Xs is in rough accord with experiment using a fairly constant glue-glue-η′ form factor. This behavior of the form factor may be indicative of glueball dominance of the channel. Searches via the modes η′h+h− (h = π or K) may be worthwhile. Implications for B → η′ + Xd and for the corresponding η modes are also given.
