Warped Compactifications: Flavor,
Unification and Dark Matter
Kaustubh Agashe
Johns Hopkins
I will begin with a brief introduction to the Randall-Sundrum (RS1) model which
uses a warped extra dimension to solve the Planck-weak hierarchy problem of the
SM. Then, I will sketch how profiles for fermions in this extra dimension can
explain also the hierarchies of quark and lepton masses (and mixing angles),
without leading to too large flavor violation in contradiction with
experiments. I will show that these fermion profiles modify running of SM gauge
couplings (from than in the SM) in such a way that we obtain gauge coupling
unification at the few percent level in a grand unified model. Finally, I will
show that requiring proton stability in this grand unified model can lead to a
stable fermion which is a good dark matter candidate. Thus, this framework is
as compelling as SUSY! I will describe how we will test it in experiments.
