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%
