SUMMARY:Lepton) Flavor Violation in SUSY GUT and Randall-Sundrum Model
 s\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Mu-Chun Chen\, U. C. I
 rvine
DESCRIPTION:In the first part of this talk\, I will discuss theoretica
 l predictions of various SUSY GUT models  for lepton flavor violation.
  Including the WMAP dark matter constraints\, lower bounds on the bran
 ch fractions of these LFV rare charged lepton decays can be obtained. 
 Furthermore\, a next generation MECO-like experiment turns out to be t
 he more robust way in distinguishing various GUT models.<br><br>

\nIn the second part of the talk\, I will focus on flavor violat
 ion in RS models. Generically\, RS models suffer from strong constrain
 ts due to the presence of the FCNCs at tree-level. Furthermore\, these
  models require fine tuning in order to get large neutrino mixing. I w
 ill present a model based on the double tetrahedral family symmetry wh
 ich successfully avoids the tree-level FCNCs in both quark and lepton 
 sectors. In addition\, our model gives rise to realistic masses and mi
 xing angles for both quarks and leptons.
