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…

CP Violating Lepton Asymmetry from B Decays in Supersymmetric Grand Unified Theories

We investigate the effect of the dimuon CP asymmetry from the B decay modes, recently observed at 3.2{sigma} deviation from the standard model (SM) by the D0 Collaboration, in the context of SU(5)

Variations on the supersymmetric Q 6 model of flavor

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

Neutral gauge boson contributions to the dimuon charge asymmetry in B decays

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

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

Reevaluating R-parity violating supersymmetry effects in $ B_s^0 - \bar{B}_s^0 $ mixing

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

Super flavorsymmetry with multiple Higgs doublets

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

Like-Sign Dimuon Asymmetry of B0 Meson and LFV in SU(5) SUSY GUT with S4 Flavor Symmetry

The like-sign dimuon charge asymmetry of the B meson, which was reported in the DO Collaboration, is studied in the SU(5) SUSY GUT model with S4 flavor symmetry. Additional CP violating effects from
