We consider more than one pair of SU(2){sub L} doublet Higgs supermultiplets in a generic supersymmetric extension of the standard model, and calculate their one-loop contributions to the soft mass insertions {delta}{sub LL} etc. We find that, if large supersymmetry breaking in this sector is realized, the loop effects can give rise to large contributions to the soft mass insertions, meaning that they can generate large flavor-changing neutral currents and CP violations. We apply our result to…

### Variations on the supersymmetric Q 6 model of flavor

• Physics
• 2011
We observe that a recently proposed supersymmetric model with ${Q}_{6}$ flavor symmetry admits a new $CP$ violating ground state. A new sum rule for the quark mixing parameters emerges, which is

Recently, the DØ Collaboration measured the CP-violating like-sign dimuon charge asymmetry in neutral B decays, finding a 3.2σ difference from the standard-model (SM) prediction. Anon-SM charge

### Implications of large dimuon CP asymmetry in Bd,s decays on minimal flavor violation with low tan β

• Physics
• 2010
The D0 collaboration has recently announced evidence for a dimuon CP asymmetry in Bd,s decays of order one percent. If confirmed, this asymmetry requires new physics. We argue that for minimally

Recently, the CDF and DØ collaborations have claimed that the CP violating phase in $B_s^0 - \bar{B}_s^0$ mixing is large, which is contrary to the expectations in the Standard Model. Such a large

The meaning of non‐Abelian super flavorsymmetry in the presence of Multiple Higgs Doublets is twofold: The first one is to order the Yukawa sector of the standard model, while generating the

We study the contribution of the squark flavor mixing from the LR(RL) component of the squark mass matrices to the direct CP violation of the b → sγ decay and the CP violating asymmetry in the
