Glueball Production via Gluonic Penguin B Decays

We study glueball G production in gluonic penguin decay B --> X_s+G, using next-to-leading order b --> s+g^* gluonic penguin interaction and an effective coupling of a glueball to two gluons. The effective coupling allows us to study the decay rate of a glueball to two pseudoscalars in the framework of chiral perturbation theory. Identifying the f_0(1710) to be a scalar glueball, we then determine the effective coupling strength with the branching ratio of f_0(1710) --> K+Kbar. We find a sizable branching ratio in the range of (2.5 ~ 5.7) x 10^{-5} for B --> X_s+G. Rare hadronic B decay data from BaBar and Belle can provide important information about glueballs
