Abstract
The unexpectedly large branching ratios for B → η′K (η′Xs) decays could be of gluonic origin. We study the implications for B → ηK (ηXs) and PK (PXs), where P is the pseudoscalar glueball. In the mechanism proposed by Fritzsch, large branching ratios are predicted for these modes. The B → ηK rate is barely within the experimental limit, and B → PK, PXs could be at the 0.1% and 1% level, respectively. Smaller but less definite results are found for the mechanism of g* → η′g via the gluon anomaly. © 1998 Published by Elsevier Science B.V. All rights reserved.
