T' - simultaneous description of quarks and leptons — •Claudia Hagedorn — Max-Planck-Institut fuer Kernphysik, Heidelberg, Deutschland

We describe an extension of a model which uses the flavor symmetry A4. This model predicts the tri-bi-maximal mixing in the lepton sector, but does not explain any features of the quark sector. We discuss properties of the quark sector by extending the flavor symmetry to T'. Then quarks and leptons transform non-trivially under this flavor symmetry.
