We present a study of B-parameters for generic S 2 four-quark operators in domain wall £ QCD. Our calculation covers all the B-parameters required to study the neutral kaon mixing in the standard model (SM) and beyond it. We evaluate one-loop renormalization factors of the operators employing the plaquette and Iwasaki gauge actions. Numerical simulations are carried out in quenched QCD with both gauge actions on 163 32 16 and 243 32 16 at the lattice¤ ¤ ¤ ¤ ¥ spacing 1 a 2GeV. We investigate the relative magnitudes of the non-SM B-parameters to the ¦ SM one, which are compared with the previous results obtained with the overlap and the clover quark actions.
