K0-K0bar on the Lattice

Abstract

I review recent lattice calculations performed with Nf=2 and Nf=2+1 dynamical fermions which provide a precise computation of the BK bag parameter. I also report on Nf=2 dynamical quark simulations aiming at the computation of the full basis of the Delta_S=2 four-fermion operator matrix elements that are relevant to models beyond the Standard Model.
