Neutral Kaon Mixing Beyond the Standard Model from 2+1 Flavour Domain Wall QCD
arXiv:0810.1841
Abstract
We present preliminary results of a study of Delta S = 2 matrix elements originating from physics beyond the Standard Model. Using 2+1 flavour Domain Wall Fermions we obtain the non-perturbative renormalisation (mixing) matrix in the RI scheme. We also discuss plans for the chiral extrapolation of the renormalised matrix elements in a partially quenched set-up.
