Progress in kaon physics on the lattice
Abstract
CKM-unitarity, direct and indirect CP-violation and the I=1/2 rule in full lattice QCD are the focus of this talk. To this end I will discuss and compare recent lattice results for leptonic, semi-leptonic and non-leptonic decays of the kaon and neutral kaon mixing and I will motivate current best estimates fK/fπ=1.198(10), f+Kπ(0)=0.964(5) and BK=0.720(39). Moreover new theoretical advances that will improve the quality of these computations in the future will be discussed.
