  24. Summary • Difference in AKp0 and AKp suggest • Non-standard EWP • 4th Generation Carries Phase • Naturally impact on EWP • With AKp predicted by PQCDF • account for AKp 0 ~ 0 if • Predictions • - b  sll on high side • - DmBs close to current bound w/ sin2FBs< 0 • -Rc - Rn OK;AK0p0~ 0.05 – 0.1,SK0p0 ~ 0.4 – 0.5 • - ACP in b  sg a fraction of SM value of 0.4% ~ SuperB Workshop in Hawaii George W.S.
