We present an extensive analysis of squark and gaugino hadroproduction and decays in
non-minimal flavour violating supersymmetry (SUSY). Within minimal flavour violation,
the flavour violating entries in the squark mass matrices are believed to stem from
the trilinear Yukawa couplings of the fermion and Higgs supermultiplets, resulting in
different renormalizations of the quark and squark...

We propose a model based on $SU(5) \times { }^{(d)}T$ which successfully gives rise to near tri-bimaximal
leptonic mixing as well as realistic CKM matrix elements for the quarks. The Georgi-Jarlskog relations for three
generations are also obtained. Due to the ${ }^{(d)}T$ transformation property of the matter fields, the $b$-
quark mass can be generated only when the ${ }^{(d)}T$...

In this talk we present a recently published extension of the MSSM which uses T' as
flavor
symmetry. The model predicts nearly tri-bi-maximal mixing in the lepton sector as well as
relates some elements of the CKM matrix to the quark mass ratios. The key point of the
model is the VEV alignment of the flavor symmetry breaking fields, i.e. tri-bi-maximal
mixing results from different...

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...

The SUSY CP and flavour puzzle is addressed in a context of recent models of flavour based on SU(3) flavour
symmetry. The leptonic tri-bimaximal mixing pattern leads to a simple effective flavour structure giving rise to
correlations among the Yukawas and the soft sector that is often enough to ensure compatibility with latest
experimental bounds.

We devise minimalist U(1)_X Froggatt-Nielsen models which give rise to the recently
proposed low-energy discrete gauge symmetry "proton hexality". The proton is thus
stable. In addition, having three generations of right-handed neutrinos we can obtain
viable neutrino masses.
Furthermore one can find scenarios such that no X-charged hidden sector superfields
are needed, which, from a...
