If the underlying flavor symmetry is Abelian, quark mixings in dR sector are the most prominent. Such flavor violating effects can reveal itself through dR squark mixings if supersymmetry is realized in Nature. Quark-squark alignment is necessary to deal with ΔmK and εK constraints, but interestingly, with m q, m g ∼ TeV, the dR mixing effects are comparable to Bd and Bs mixings in the Standard Model, while D0 mixing is tantalizingly close to some hints from data. CP phases in these mixings would therefore be deviant, and | Vtd| and arg Vub^* may be larger than allowed by unitarity constraints, which can be checked by the BaBar and Belle experiments. Mixing induced CP violation in b→ sγ and dγ transitions can be obtained, in particular, by sizable enhancement with an extra tanβ factor from non-standard soft breaking terms. Heavy superparticles can escape present flavor changing neutral current (FCNC) bounds and direct searches at colliders, but reveal themselves in the B system.
