Query: Linking Natural Supersymmetry to Flavour Physics   With the aim of linking natural supersymmetry to flavour physics, a model is
proposed based on a family symmetry G \times U(1), where G is a discrete
nonabelian subgroup of SU(2), with both F-term and (abelian) D-term
supersymmetry breaking. A good fit to the fermion masses and mixing is obtained
with the same U(1) charges for the left- and right- handed quarks of the first
two families and the right-handed bottom quark, and with zero charge for the
left-handed top-bottom doublet and the the right handed top. The model shows an
interesting indirect correlation between the correct prediction for the
V_{ub}/V_{cb} ratio and large right-handed rotations in the (s,b) sector,
required to diagonalise the Yukawa matrix. For the squarks, one obtains almost
degenerate first two generations. The main source of the FCNC and CP violation
effects is the splitting between the first two families and the right-handed
sbottom determined by the relative size of F-term and D-term supersymmetry
breaking. The presence of the large right-handed rotation implies that the
bounds on the masses of the first two families of squarks and the right handed
sbottom are in a few to a few tens TeV range. The picture that emerges is light
stops and left handed sbottom and much heavier other squarks.
