312. Squark and gaugino hadroproduction and decays in non-minimal flavour violating supersymmetry

Flavor Physics

Parallel Talk

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...

Parallel Talk

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 ${ }^{(d)}T$...

256. A_4 and its double-covering T' as flavor symmetries

Parallel Talk

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...

Parallel Talk

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...

363. SUSY CP and Flavour in SUGRA flavour models with tri-bimaximal lepton mixing

Dr Michal Malinsky (University of Southampton)

Flavor Physics

Parallel Talk

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.

132. Proton hexality from an anomalous flavor U(1)

Parallel Talk

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...
