Strong Anomalies in Kaon Decays
S. Trine
Abstract
We point to a potentially large contribution of the QCD trace anomaly to the isoscalar pion pair production in Kaon decays. This contribution arises from the long-distance evolution of a 7-dimensional quark-gluon operator generated by short-distance QCD corrections to the DeltaS = 1 Fermi Hamiltonian.
