SUMMARY:The Higgs\, Flavor and Large At in Extended GMSB\, Theory Semi
 nar (High Energy/Cosmology)\, Jared Evans
DESCRIPTION:The observed Higgs at 126 GeV requires large tuning in the
  MSSM.  This tuning is particularly bad in gauge mediated SUSY breakin
 g (GMSB)\, as the large A-terms that can ameliorate this tuning are ab
 sent at the messenger scale.  Extending GMSB through the addition of s
 uperpotential couplings between the MSSM and messenger superfields can
  generate these A-terms to reduce the severity of the tuning problems 
 in GMSB.  There are a variety of couplings that one can consider\, but
  those best for tuning provide a source of flavor violation beyond the
  standard model Yukawas.  However\, there are several features of the 
 extended GMSB models that allow them to relax the SUSY flavor problem.
   I will review extended GMSB\, discuss these flavor issues in detail\
 , and also discuss some of the phenomenological prospects for discover
 ing these models.
