Enhanced b→sg decay, inclusive η′ production, and the gluon anomaly

The experimental hint of large B --> eta' + X-s is linked to the b --> s penguins via the gluon anomaly. Using running alpha(s) in the eta'-g-g coupling, the standard b --> sg* penguin alone seems insufficient, calling for the need dipole b --> sg at the 10% level from new physics, which could also resolve the semileptonic branching ratio and charm counting problems. The interference of standard and new physics contributions may result in direct CP asymmetries at the 10% level, which could be observed soon at B factories.
