Sommaire:

The absence of any significant deviations from the SM in flavor observables requires new physics at the TeV scale to have a highly non-trivial flavor structure. This suggests a relation to the SM flavor puzzle, i.e. the hierarchical structure of fermion masses and mixing. After a short introduction to the SUSY flavor problem I will discuss two possible solutions presented in arXiv:1304.1453 and arXiv:1308.1090. In the first case a deformation of gauge mediation with new messenger-matter couplings controlled by a simple flavor symmetry leads to strong suppression of sfermion flavor violation. In the second case a SU(2)xU(1) flavor model allows to neatly explain the quark Yukawa structure and gives rise to a natural SUSY spectrum in which only the sfermions are light that are required by Naturalness.
