Using Lattice QCD and ChPT to obtain non-leptonic K-decay amplitudes
Maarten Golterman, Elisabetta Pallante
Abstract
We summarize some of the difficulties that confront lattice calculations of non-leptonic kaon decay matrix elements. We review some of the methods that have been proposed to overcome these difficulties, and discuss the importance of one-loop ChPT in this respect, including the role of O(p4) operators.
