In the light of recent experimental anomalies indicating a non-zero
Bs-Bs-bar mixing phase I present a fresh look at meson-antimeson mixing in
the MSSM. I present a new analysis of the up-type and down-type squark
mass matrices with focus on constraints on the mass splittings among the
first two generations of left-handed squarks. If the gluino is heavier
than the squarks, the...

Flavor symmetry
combined with spontaneous CP violation
is used suppress CP violation
in susy extension of the SM.
We show how this works in a concrete model
based on a discrete flavor group Q6.
We find there is a built-in mechanism
in the model to enhance the suppressed CP violation
in the B meson system, and we compare
our result with the resent results from
D0 and CDF.

Discrete symmetries employed to explain flavor mixing and mass hierarchies are often associated with an enlarged scalar sector which might lead to exotic Higgs decay modes. We explore such a possibility in a scenario with S_3 flavor symmetry which requires three scalar SU(2) doublets. The spectrum is fixed by minimizing the scalar potential, and we observe that the symmetry of the model leads...

We discuss the flavor symmetries of the three-site model at tree-level and beyond and consider the general bounds on flavor structure of the three-site model arising from neutral-meson mixing phenomenology, constraints on lepton flavor violation, and precision electroweak measurements.

We propose a supersymmetric extension of the standard model based on the flavor symmetry A4. Charged fermion masses arise from renormalizable Yukawa couplings while neutrino masses are generated by the usual dimension five operator. We show that by a suitable choice of the soft breaking terms one
can reproduce all fermion mass hierarchies, predicting a mass formula relating down quarks and...
