Lepton) Flavor Violation in SUSY GUT and Randall-Sundrum Models
Date: Friday, November 13th
Time: 2:30 pm
Place: 2301 Sterling Hall
Speaker: Mu-Chun Chen, U. C. Irvine
Abstract: In the first part of this talk, I will discuss theoretical predictions of various SUSY GUT models for lepton flavor violation. Including the WMAP dark matter constraints, lower bounds on the branch fractions of these LFV rare charged lepton decays can be obtained. Furthermore, a next generation MECO-like experiment turns out to be the more robust way in distinguishing various GUT models.<br>

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