New Physics Scenarios in B hh

April 20, 20052nd SuperB Workshop @ Hawaii

SuperB Workshop in Hawaii

George W.S. Hou

- Intro: NP in EWP?
- PQCDF and AKp
- but AKp0 ?
- Why 4th Generation?
- Results

- 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%

have similar behavior

No existence of a region of the parameter space

where the asymmetries fit the experimental data
