Description
With the increasing precision on experimental information from flavour violating
processes,it is possible to constraint severely theories with horizontal symmetries.
These horizontal symmetries, which explain successfully the masses and mixings of
fermions, often produce off-diagonal terms in the supersymmetric soft squared mass
matrices and in the trilinear terms of the corresponding super-partners, at the scale
at which such symmetries are broken. Hence in some cases at electroweak scale these
may in fact produce off-diagonal terms that exceed the allowed bounds on flavour
changing effects. However in other cases the allowed supersymmetric mass spectrum is
enhanced in comparison to that produced assuming the minimal supergravity boundary
conditions at high scale. In this talk I will classify those theories which enhance
the allowed range of supersymmetric mass spectrum and theories which are likely to be
ruled out by upcoming precision on relevant experimental information.
