Electroweak penguins and SUSY K0-K¯0 mixing with Neuberger quarks

We present results for ΔI=3/2 and ΔS=2 matrix elements relevant for CP violation in K→ππ decays and for the KS−KL mass difference in the standard model and beyond. They were obtained with Neuberger fermions on quenched gauge configurations generated with the Wilson plaquette action at β=6.0 on an 183×64 lattice.
