SUMMARY:Majorana Physics Through the Cabibbo Haze\, Theory Seminar (Hi
 gh Energy/Cosmology)\, Jue Zhang\, University of Florida
DESCRIPTION:Motivated by SO(10)\, where the charge two-thirds and neut
 ral Dirac Yukawa matrices are related\, we propose a special form of t
 he seesaw Majorana matrix. It not only can mitigate the severe hierarc
 hy of the quark sector\, but also contains a Gatto-Sartori-Tonin like 
 relation\, which predicts specific values for the light neutrino masse
 s. Two different ways of obtaining that special Majorana matrix from t
 he family symmetry $Z_7 rtimes Z_3$ will be presented. The first way r
 equires a linear combination of two dimension-five family invariant op
 erators\, while in the second one a single dimension-six operator is n
 eeded.
