"QCD ANOMALIES IN HADRONIC WEAK DECAYS"



Abstract








The flavour-changing operators associated with the strong axial and trace anomalies are considered. Their short-distance generation through penguin-like diagrams is obtained within the QCD external field formalism.
Standard-model operator evolution exhibits a suppression of anomalous effects in K and B hadronic weak decays. A genuine set of dimension-eight Delta S = 1 operators is also displayed.
