Fermion Hierarchy from Sfermion Anarchy

Understand

We present a framework to generate the hierarchical flavor structure of Standard Model quarks and leptons from loops of superpartners.

• The simplest model consists of the minimal supersymmetric standard model with tree level Yukawa couplings for the third generation only and anarchic squark and slepton mass matrices.
• Agreement with constraints from low energy flavor observables, in particular Kaon mixing, is obtained for supersymmetric particles with masses at the PeV scale or above.
• In our framework both the second and the first generation fermion masses are generated at 1-loop.
