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%
