Description

Quenching effects in strong penguin matrix elements are investigated. A lattice determination of αqNS, the constant that appears in the quenched ChPT relevant for the lattice analysis of K->ππ matrix elements, shows that this constant is large. The original RBC analysis of Q6 matrix elements is revisited in light of this result. Also, the numerical effects of choosing the singlet Golterman-Pallante method of quenching Q6 is investigated
