Abstract

We compute the hadronic matrix elements of the four-quark operators needed for the study of $K^0-{\bar K^0}$ mixing beyond the Standard Model. We have used $n_f=2+1$ flavours of domain wall fermion (DWF) at two values of the lattice spacing ( $a\approx0.08$ and $a\approx0.11\text{fm}$ ) and with lightest unitary pion mass of $\approx300\,\text{MeV}$ . Renormalisation is performed non-perturbatively and the impact of different intermediate momentum schemes is investigated.

Keywords

non-perturbative renormalization in lattice qcd quark and lepton masses and mixing lattice qcd
