On the Singlet Penguin in B --> K eta' decay

Abstract

New contributions to the short-distance b --> s eta' transition are considered. They correspond to the quark and gluon content of eta'. Although substantially larger than the referent QCD anomaly tail, they still cannot account for the observed eta' enhancement.
