摘要：By studying the origin of supersymmetry (SUSY) contributions that could
impact on B0
d{B0
d mixing and B ! decay, we nd that the former is sensitive to leftleft
or right-right squark mixings, while the latter is sensitive to left-right squark mixings.
These two processes in general are not much correlated in SUSY models. If the smallness
of B ! is due to SUSY models, one would likely have large B ! from chiral
enhancement, and the rate could be within present experimental reach. Even if B !
is not greatly enhanced, it could have large mixing dependent CP violation.
