SUMMARY:Discrete flavor symmetries for lepton mixing and quark mixing - At
 sushi Ogasahara\, Kyoto University

DESCRIPTION:A non-Abelian discrete flavor symmetry is an important candida
 te for\nexplaining the patterns of the lepton mixing and the quark mixing.
  In\nthe lepton mixing\, the tri-bimaximal pattern is an interesting\nappr
 oximation for $\\theta_{13}=0$ and many models have been proposed so far. 
 However\, the recent experiments show large $\\theta_{13}$\, so we need so
 me modifications. One way of modifications is to take an alternative flavo
 r symmetry\, which generates non-zero $\\theta_{13}$ at the leading order.
  On the other hand\, the pattern of the quark mixing is another mystery in
  the Standard Model. Since the Cabibbo angle is as large as $\\theta_{13}$
  in the lepton mixing\, the Cabibbo angle could also be generated by the f
 lavor symmetry. In this talk\, through the systematic search for flavor sy
 mmetries\, we propose a flavour symmetry which generates both the lepton m
 ixing and the Cabibbo angle.
