Abstract

Recently, we pointed out that chiral transformation properties of penguin operators change in the transition from unquenched to (partially) quenched QCD. As a consequence, new operators appear in (partially) quenched QCD penguins, introducing ambiguities which should be considered a quenching artifact. Here we discuss more specifically the effects of this phenomenon on the quenched ΔI = 1/2 K → ππ amplitude, and in particular, its potential numerical effect on recent lattice estimates for ε′/ε.
