12 Sep 2007 | | Abstract: | We explore how to protect extra dimensional models from large flavor changing
neutral currents by using bulk and brane flavor symmetries. We show that a GIM
mechanism can be built in to warped space models such as Randall-Sundrum or
composite Higgs models if flavor mixing is introduced via UV brane kinetic
mixings for right handed quarks. We give a realistic implementation both for a
model with minimal flavor violation and one with next-to-minimal flavor
violation. The latter does not suffer from a CP problem. We consider some of
the existing experimental constraints on these models implied by precision
electroweak tests. | | Source: | arXiv, 0709.1714 | | Services: | Forum | Review | PDF | Favorites | |
